How To Tell If A Digital Forensics Expert Is Qualified
Digital evidence plays a pivotal role in everything from corporate investigations and criminal trials to trucking accidents and insurance fraud. Finding a qualified digital forensics expert has never been more important.
As I covered in my last article, digital forensics differs from many professional fields in that it lacks a universal licensing requirement. This absence leaves attorneys, judges, and organizations with the difficult task of evaluating expert qualifications without any standardized criteria to guide their decisions.
So how can you determine if a digital forensics expert is truly qualified to handle your case? The answer lies in understanding the unique qualification landscape created through formal education, certifications and experience.
Academic credentials in digital forensics, computer science or cybersecurity provide a structured foundation of knowledge that can be valuable in establishing an expert's qualifications. Degrees from accredited institutions demonstrate that an individual has completed a comprehensive curriculum covering fundamental concepts and methodologies relevant to digital investigations.
However, formal education comes with inherent limitations in this rapidly evolving field. Many highly skilled digital forensics professionals enter the discipline from diverse backgrounds in IT, law enforcement, military intelligence and law, bringing valuable perspectives that traditional academic paths might not provide. Some of the most effective practitioners developed their expertise through non-traditional routes, accumulating specialized knowledge through hands-on experience rather than classroom instruction.
Even when formal education is present, the static nature of academic curricula presents challenges. University programs must maintain a certain level of consistency, meaning coursework often lags behind the cutting-edge of technology. A degree completed five years ago could provide solid foundations for the overarching principles of mobile phone forensics, but it wouldn't cover today's mobile forensics challenges. Challenges that evolve with every iOS and Android operating system update.
This reality underscores why the most qualified digital forensics experts approach their profession as lifelong learners, continuously supplementing their formal education with ongoing professional development. The best practitioners actively seek knowledge beyond their initial training, regardless of whether that training occurred in a university setting or through alternative pathways.
While not mandatory, certifications provide an important baseline for assessing a digital forensics expert's technical knowledge. These credentials fall into two main categories, each offering different insights into an expert's capabilities:
The strongest digital forensics experts typically possess a combination of both certification types, showing both practical tool mastery and broader methodological understanding. This certification portfolio provides reasonable assurance that an expert possesses at least minimum technical competency. However, certifications alone tell only part of the qualification story.
While certifications establish baseline knowledge, real-world experience often proves the most valuable in determining an expert's true capabilities. Digital forensics is fundamentally a practical discipline where theoretical knowledge must be applied to complex, unique scenarios that rarely match textbook examples—because an examiner may be the first to encounter a new type of digital evidence.
When evaluating experience, consider both quantity and quality. The number of years in practice matters, but more important is the diversity and complexity of cases handled. An expert who has worked five years exclusively doing forensic data collections may have less relevant expertise than someone with three years of experience across criminal, civil, and regulatory matters involving diverse technical challenges.
An expert may possess extensive technical knowledge but struggle to effectively communicate findings to judges and juries. Previous testimony experience—especially in cases similar to yours—suggests an expert can translate complex technical concepts into language accessible to non-technical audiences.
Publication history and continuing education also signal an expert's commitment to the field. Digital forensics evolves rapidly as technology changes, making ongoing learning essential. Experts who regularly attend conferences, participate in professional organizations, or contribute to peer-reviewed literature demonstrate they're engaged with emerging developments that may prove crucial to your case.
Perhaps the most overlooked aspect of digital forensics qualification is the field's extensive specialization. Digital forensics encompasses numerous distinct sub-disciplines, each requiring specialized knowledge and techniques. This specialization means that even highly qualified experts may lack relevant expertise for specific case types.
Consider the stark differences between sub-disciplines:
A computer forensics expert may excel at recovering deleted files from laptops and analyzing user activity on desktop systems, but lack the specialized knowledge needed for cell site location analysis that could establish a suspect's whereabouts during a critical timeframe.
Similarly, a video forensics expert skilled at authenticating and enhancing surveillance footage might have little experience with mobile device forensics necessary to recover deleted messaging app data from a smartphone.
Even within seemingly related areas, critical differences exist. A network forensics specialist who routinely investigates corporate data breaches may lack the specific expertise needed to properly investigate peer-to-peer child exploitation cases.
This specialization means you must assess qualification specifically for your case's technical requirements. An expert with impressive credentials and extensive experience may still be the wrong choice if their expertise doesn't align with your specific technical needs.
When evaluating potential experts, ask pointed questions about their experience with the precise technologies and scenarios relevant to your matter. Request case examples demonstrating successful work in your specific sub-discipline. The most qualified expert for your case isn't necessarily the one with the most impressive overall resume, but rather the one with the most relevant specialized expertise.
Beyond credentials and experience, how an expert approaches their work reveals much about their qualification. Digital forensics demands rigorous methodology to ensure evidence integrity and reliable findings.
Qualified experts should clearly explain how they follow established methodological standards from organizations like the Scientific Working Group on Digital Evidence, or SWGDE, or the National Institute of Standards and Technology, or NIST. They should keep detailed documentation of their processes, including chain of custody procedures, tool validation methods, and analytical techniques.
Transparency about limitations is equally important. The best experts acknowledge the boundaries of what digital evidence can reliably show and avoid making overreaching conclusions. They should openly discuss potential alternative explanations for their findings and clearly distinguish between factual observations and interpretive opinions.
This methodological rigor separates truly qualified experts from those who may have impressive credentials but lack the disciplined approach needed for forensically sound work.
Determining if a digital forensics expert is qualified requires looking beyond any single credential or experience to evaluate their complete professional profile. The most qualified experts show technical competence through certifications, practical capability through relevant experience, specialized knowledge in your specific sub-discipline and methodological rigor in their approach.
For attorneys and organizations seeking digital forensics expertise, this holistic assessment approach takes more effort than simply checking for a license or certification. However, this investment in thorough qualification evaluation pays off through reliable digital evidence analysis that can withstand scrutiny in legal proceedings.
In a field where technology changes daily and new challenges constantly emerge, the most qualified digital forensics experts aren't just those with static credentials, but those who combine foundational knowledge with specialized expertise and a commitment to methodological excellence. By evaluating potential experts across these dimensions, you can find truly qualified professionals capable of handling your specific digital evidence needs.

'Dark cloud' hangs over cruise industry as complaints of crimes rise in recent years — how to stay safe at sea
Complaints of crimes and missing person reports on cruises that dock at U.S. ports have surged in recent years, fueling what one security expert calls a 'dark cloud' over an industry eager to protect its reputation. Department of Transportation figures show 48 alleged incidents between Jan. 1 and March 30 of this year: 23 reports of rape, 10 of other forms of sexual assault, seven of physical assault and seven of theft greater than $10,000. One missing U.S. national was also reported. Thanks to Jeff Bezos, you can now become a landlord for as little as $100 — and no, you don't have to deal with tenants or fix freezers.

Find out how you can access this $1B private real estate fund (with as little as $10) There were also 47 alleged incidents in each of the first and third quarters of 2024, 50 in the fourth quarter of 2023 and 55 in the second quarter of 2023. 'All of that negative vibe and negative information puts a dark cloud over the industry,' Robert McDonald, a former Secret Service agent and lecturer on criminal justice at the University of New Haven, told Fox News in a story published May 15. Cruise lines 'want [passengers] to be comfortable spending their money.' A spokesperson for the Cruise Lines International Association told Fox News that 'crime is extremely rare on cruise ships' thanks to strict security vetting and training that "make cruise[s] one of the safest holiday options.' A mixture of large groups of people, alcohol and the sense of freedom that comes with being on vacation can create an environment that's more prone to illicit activity, says McDonald. 'Anytime we get together, those numbers are going to go up, whether that's at a resort, whether it's on a cruise ship,' he said. Among recent reports: On March 21, two men in their 30s were arrested, accused of raping a 14-year-old boy in a sauna aboard a Royal Caribbean cruise ship, reports the Miami Herald. Both men were charged with sexual battery of a minor, exposing themselves to a minor and molestation of a child aged 12 to 16. One man faced an additional charge of not informing another person in a sexual act of his HIV status. 'We take these allegations very seriously and immediately notified local law enforcement,' a Royal Caribbean Group spokesperson told the Herald. Read more: Want an extra $1,300,000 when you retire? Dave Ramsey says — and that 'anyone' can do it A month later, dozens of Carnival Cruise Line passengers were banned after video of a brawl at a Galveston, Texas, terminal emerged on social media showing people kicking and punching one another as they disembarked, according to Fox News. Carnival told the news outlet the matter was referred to law enforcement, and stressed that the company 'will not tolerate such behavior.' While reports of alleged crime on the high seas may be elevated, some experts insist cruises remain a safe way to travel. If you choose to cruise, you can be proactive and make sure you understand the laws that can help keep you safe. Jurisdiction on cruise ships is a constantly moving target that can change after a vessel moves away from shore. Within 12 nautical miles of the coast, the coastal nation's criminal code typically applies; beyond 12 miles, the ship falls under the law of the country whose flag it flies. Maritime laws may also apply. Before you sail, make sure you understand which laws and regulations will apply during your trip. Statistics for reports of alleged crimes of major cruise operators appear in quarterly Department of Transportation reports, and the CDC publishes sanitation scores for each ship. This can help you decide which cruise line and which ship you're comfortable sailing on. Cruise ships have internal emergency systems, including dedicated phone lines.

No Supreme Court win, but Mexico pressures U.S. on southbound guns
More than a decade ago, Mexican authorities erected a billboard along the border in Ciudad Juárez, across the Rio Grande from El Paso. "No More Weapons," was the stark message, written in English and crafted from 3 tons of firearms that had been seized and crushed. It was a desperate entreaty to U.S. officials to stanch the so-called Iron River, the southbound flow of arms that was fueling record levels of carnage in Mexico. But the guns kept coming — and the bloodletting and mayhem grew. Finally, with homicides soaring to record levels, exasperated authorities pivoted to a novel strategy: Mexico filed a $10-billion suit in U.S. federal court seeking to have Smith & Wesson and other signature manufacturers held accountable for the country's epidemic of shooting deaths. The uphill battle against the powerful gun lobby survived an appeals court challenge, but last week the U.S. Supreme Court threw out Mexico's lawsuit, ruling unanimously that federal law shields gunmakers from nearly all liability. Read more: So what really happened at the cartel training site dubbed 'Mexican Auschwitz'? Although the litigation stalled, advocates say the high-profile gambit did notch a significant achievement: Dramatizing the role of Made-in-U.S.A. arms in Mexico's daily drumbeat of assassinations, massacres and disappearances. "Notwithstanding the Supreme Court ruling, Mexico's lawsuit has accomplished a great deal," said Jonathan Lowy, president of Global Action on Gun Violence, a Washington-based advocacy group. "It has put the issue of gun trafficking — and the industry's role in facilitating the gun pipeline — on the bilateral and international agenda," said Lowy, who was co-counsel in Mexico's lawsuit. Read more: Supreme Court throws out Mexico's suit against U.S. gun makers in a unanimous decision A few hours after the high court decision, Ronald Johnson, the U.S. ambassador in Mexico City, wrote on X that the White House was intent on working with Mexico "to stop southbound arms trafficking and dismantle networks fueling cartel violence." The comments mark the first time that Washington — which has strong-armed Mexico to cut down on the northbound traffic of fentanyl and other illicit drugs — has acknowledged a reciprocal responsibility to clamp down on southbound guns, said President Claudia Sheinbaum. She hailed it as a breakthrough, years in the making. "This is not just about the passage of narcotics from Mexico to the United States," Sheinbaum said Friday. "But that there [must] also be no passage of arms from the United States to Mexico." Mexico is mulling options after the Supreme Court rebuff, Sheinbaum said. Still pending is a separate lawsuit by Mexico in U.S. federal court accusing five gun dealers in Arizona of trafficking weapons and ammunition to the cartels. Read more: Indigenous activist's disappearance and killing cause outcry in Mexico's Oaxaca state Meanwhile, U.S. officials say that the Trump administration's recent designation of six Mexican cartels as foreign terrorist organizations means that weapons traffickers may face terrorism-related charges. "In essence, the cartels that operate within Mexico and threaten the state are armed from weapons that are bought in the United States and shipped there," U.S. Secretary of State Marco Rubio told a congressional panel last month. "We want to help stop that flow." On Monday, federal agents gathered at an international bridge in Laredo, Texas, before an array of seized arms — from snub-nosed revolvers to mounted machine guns — to demonstrate what they insist is a newfound resolve to stop the illicit gun commerce. "This isn't a weapon just going to Mexico," Craig Larrabee, special agent in charge of Homeland Security Investigations in San Antonio, told reporters. "It's going to arm the cartels. It's going to fight police officers and create terror throughout Mexico." Read more: Trump wants to attack drug cartels. How can Mexico respond if he does? In documents submitted to the Supreme Court, Mexican authorities charged that it defied credibility that U.S. gunmakers were unaware that their products were destined for Mexican cartels — a charge denied by manufacturers. The gun industry also disputed Mexico's argument that manufacturers deliberately produce military-style assault rifles and other weapons that, for both practical and aesthetic reasons, appeal to mobsters. Mexico cited several .38-caliber Colt offerings, including a gold-plated, Jefe de Jefes ("Boss of Bosses") pistol; and a handgun dubbed the "Emiliano Zapata," emblazoned with an image of the revered Mexican revolutionary hero and his celebrated motto: "It is better to die standing than to live on your knees." Compared with the United States, Mexico has a much more stringent approach to firearms. Like the 2nd Amendment, Mexico's Constitution guarantees the right to bear arms. But it also stipulates that federal law 'will determine the cases, conditions, requirements and places' of gun ownership. There are just two stores nationwide, both run by the military, where people can legally purchase guns. At the bigger store, in Mexico City, fewer than 50 guns are sold on average each day. Buyers are required to provide names, addresses and fingerprints in a process that can drag on for months. And unlike the United States, Mexico maintains a national registry. But the vast availability of U.S.-origin, black-market weapons undermines Mexico's strict guidelines. According to Mexican officials, an estimated 200,000 to half a million guns are smuggled annually into Mexico. Data collected by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives illustrate where criminals in Mexico are obtaining their firepower. Of the 132,823 guns recovered at crime scenes in Mexico from 2009 to 2018, fully 70% were found to have originated in the U.S. — mostly in Texas and other Southwest border states. In their lawsuit, Mexican authorities cited even higher numbers: Almost 90% of guns seized at crime scenes came from north of the border. Experts say most firearms in Mexico are bought legally at U.S. gun shows or retail outlets by so-called straw purchasers,who smuggle the weapons across the border. It's a surprisingly easy task: More than a million people and about $1.8 billion in goods cross the border legally each day, and Mexico rarely inspects vehicles heading south. In recent years, the flood of weapons from the United States has accelerated, fueling record levels of violence. Mexican organized crime groups have expanded their turf and moved into rackets beyond drug trafficking, including extortion, fuel-smuggling and the exploitation of timber, minerals and other natural resources. In 2004, guns accounted for one-quarter of Mexico's homicides. Today, guns are used in roughly three-quarters of killings. Mexican leaders have long been sounding alarms. Former President Felipe Calderón, who, with U.S. backing, launched what is now widely viewed as a catastrophic "war" on Mexican drug traffickers in late 2006, personally pleaded with U.S. lawmakers to reinstate a congressional prohibition on purchases of high-powered assault rifles. The expiration of the ban in 2004 meant that any adult with a clean record could enter a store in most states and walk out with weapons that, in much of the world, are legally reserved for military use. 'Many of these guns are not going to honest American hands,' Calderon said in a 2010 address to the U.S. Congress. 'Instead, thousands are ending up in the hands of criminals.' It was Calderón who, near the end of his term, ventured to the northern border to unveil the massive billboard urging U.S. authorities to stop the weapons flow. His appeals, and those of subsequent Mexican leaders, went largely unheeded. The verdict is still out on whether Washington will follow up on its latest vows to throttle the gun traffic. "The Trump administration has said very clearly that it wants to go after Mexican organized crime groups," said David Shirk, a political scientist at San Diego University who studies violence in Mexico. "And, if you're going to get serious about Mexican cartels, you have to take away their guns." Special correspondent Cecilia Sánchez Vidal contributed to this report.

The National Guard comes to Los Angeles: What's going to happen? Is it legal?
The Trump administration says it will send 2,000 National Guard troops to Los Angeles after two days of isolated clashes between federal immigration agents and protesters. Officials say the Guard will assist in operations related to Trump's crackdown on illegal immigration. Many questions remain unanswered, but here is what we know: Officials said the troops were arriving in L.A. as soon as Saturday night, though it was unclear when the full 2,000 personnel would be in place. Secretary of Defense Pete Hegseth said on X that the Guard was being deployed "immediately to support federal law enforcement in Los Angeles. And, if violence continues, active duty Marines at Camp Pendleton will also be mobilized — they are on high alert." Tom Homan, the Trump administration's 'border czar,' said on Fox News that officials were trying to "address violence and destruction occurring near raid locations where demonstrators are gathering. ... American people, this is about enforcing the law, and again, we're not going to apologize for doing it." It is possible they will provide backup during future immigration raids and prove protection of some federal facilities, including a detention center in downtown L.A. has was the scene of protests and some vandalism; California Gov. Gavin Newsom sid local law enforcement was already mobilized and that sending in troops was a move that was 'purposefully inflammatory' and would 'only escalate tensions.' '[T]here is currently no unmet need,' Newsom said. Trump said in a memo to the Defense and Homeland Security departments that he was calling the National Guard into federal service under a provision called Title 10 to 'temporarily protect ICE and other United States Government personnel who are performing Federal functions.' Title 10 provides for activating National Guard troops for federal service. Such Title 10 orders can be used for deploying National Guard members in the United States or abroad. Erwin Chemerinsky, dean of UC Berkeley School of Law, said in a text to The Times that Trump has the authority under the Insurrection Act of 1807 to federalize the National Guard units of states to suppress 'any insurrection, domestic violence, unlawful combination, or conspiracy' that 'so hinders the execution of the laws.' Yes, the National Guard has been deployed to Los Angeles numerous times amid civil unrest and natural disaster. Jessica Levinson, a law professor at Loyola Law School, noted that when the National Guard was sent to L.A. before, it was because California requested it and the response was coordinated. In 2020, widespread criminal acts in the wake of the George Floyd murder prompted Mayor Eric Garcetti to seek National Guard troops from Newsom. Garcetti asked for 1,000 troops. Guardsmen toting M-4 rifles could be seen patrolling streets between Skid Row and Bunker Hill. In combat gear, they stood guard outside shattered storefronts and graffiti-tagged buildings, where windows had been shattered and the street strewn with trash. Humvees and military trucks were present in the city. In 1994, after a 6.7 earthquake left more than 1,000 buildings destroyed and 20,000 residents homeless, the Guard was brought in. Convoys rumbled through the San Fernando Valley, patrolling mini-malls and parks to deliver water, deter looters, direct traffic and raise tent cities for 6,000 displaced residents. In 1992, thousands of National Guard and U.S. military troops patrolled L.A. amid the riot following the Rodney King trial. Mayor Tom Bradley requested the help when the LAPD could not quell the unrest. In 1965, 13,000 troops were sent to L.A. amid the Watts riots.
