LAUREL, Md. — The car jolted as protesters pounded on its windows, boxing in the lawmaker trapped inside. Within seconds, officers in full riot gear surged forward in formation, yanking open the doors and pulling the passenger to safety. A few hundred yards away, another team of police moved just as quickly, surrounding, isolating and arresting a man spotted in the crowd with a gun.
The clashes were staged, unfolding Friday at a Secret Service training complex in Maryland. U.S. Capitol Police led the operation, joined by 600 officers representing nearly 20 agencies — including the Secret Service and local police and sheriff’s departments — in one of the largest law enforcement training drills in the country. The goal was to sharpen coordination among the many agencies that must work side by side in Washington, a push shaped by the glaring security breakdowns of the .

With 2025 on track to bring more than ever before, law enforcement agencies are bracing for a volatile era defined by surging political violence and swelling protest movements.

Lessons learned from Jan. 6, 2021, Capitol riot
The training highlighted how quickly multiple dangers can erupt at once, and how determined authorities are to prepare for the next flashpoint.
The exercise came as threats and attacks against public officials mount, and federal authorities step more aggressively into cities to confront unrest. From the storming of the Capitol to more recent attacks targeting and , the scenarios practiced in Friday’s drill carried an unmistakable resonance: In today’s America, the line between routine dissent and potential disaster feels increasingly thin.
Commanders emphasized that the drills are not just about riot shields and tactical maneuvers. They also showcased new tools meant to prevent the kinds of communication breakdowns that . Drones provided real-time aerial views of the mock protests, while mobile command posts allowed leaders from different agencies to track the action simultaneously and direct units on the ground.
Officials said the biggest shift since Jan. 6, 2021, was the rhythm of coordination itself. Agencies that once trained largely in isolation now drill together, building muscle memory for rapid deployments and cross-agency communication that can determine whether a protest remains peaceful or spirals into violence.

U.S. Capitol Police Chief Michael Sullivan speaks to reporters Friday during a training exercise involving local and federal law enforcement.
“Training like this is incredibly important,” said Michael Sullivan, chief of the U.S. Capitol Police. “Making sure that we understand how the different teams work is critically important if we ever have to make that call for them to come in and help.”
The push reflects how deeply the Capitol riot still looms over the force. Sean Gallagher, an assistant chief who oversaw the department’s response to scathing inspector general and , said the agency is not ignoring those failures. Instead, he cast the drill as a deliberate attempt to turn lessons into action.
Reflecting on the mistakes of the past, Gallagher said the agency wouldn’t shy away from them, but “this is our attempt at fixing those issues.”
He added: “We’re facing a lot of different threats. It’s a heightened political environment that we continuously operate in on Capitol Hill. We’ve taken the lessons of the past, we’ve incorporated them into these scenarios and the goal with this is to be proactive and not reactive.”

That urgency is felt not just in the command ranks but also on the front lines. Aaron Davis, a Capitol Police officer who worked on the civil disturbance unit for nearly eight years and responded to the riot, said the drills are essential because no scenario feels implausible anymore.
“We use our imagination like crazy in training, just because you don’t want that to be the first time you encounter something of that nature,” he said, recalling the storming of the Capitol that left hundreds of his fellow officers injured.

Realistic drills for volatile era marked by unrest
In other scenarios, demonstrators shouted “Free D.C.” as they hurled wooden blocks meant to simulate bricks — a nod to the rising anger over the into the nation’s capital. “Keep moving, back up!” officers yelled as they marched the crowd down the street behind riot shields, while an unmarked police van pulled in to carry away those taken off in handcuffs.
The realism of the drills, officials said, was intentional: Each scenario was designed to mirror the volatile mix of protest and confrontation that is increasingly common in American cities.

U.S. Secret Service Uniformed Division Assistant Chief Andrew Ackley speaks to reporters Friday during a training exercise.
For the Secret Service, the lessons stretch back to the that filled Washington in 2020 during President Donald Trump’s first administration.
Andrew Ackley, assistant chief of the agency’s Uniform Division, said those experiences underscored how much tactics must change as threats evolve.
“The training has evolved significantly because we’re constantly learning. None of these situations are identical, right? None of these situations can be copycat from another one,” he said. “So we’re constantly evolving. We’re constantly training.”
More states are filling a federal gap by helping police track stolen guns
More states are filling a federal gap by helping police track stolen guns

On Dec. 6, 2024, Connecticut State Police arrested a 35-year-old man who had allegedly failed to report several of his guns as stolen.
It wasn't a mundane arrest: His appeared to be a classic example of gun trafficking fueled by straw purchasing, a term for when a person buys a gun with the intent of giving or selling it to someone prohibited from possessing it, like a person convicted of a felony. In all, the man had allegedly purchased more than 30 guns, including 16 in 2020 alone. Some resurfaced in criminal investigations in Connecticut and neighboring New York.
A Connecticut law that requires gun owners to report lost or stolen firearms aided the investigation.
In 2017, that just 11 states had requirements for reporting lost and stolen guns on the books. Six more states have adopted them since then, bringing the total to 17. This year, as legislative sessions heat up, at least four states may vote on bills to enact new requirements, and two more are considering bills that could strengthen existing requirements.
These mandates fill a gap in federal law: While firearms dealers are required to report lost or stolen guns within 48 hours, there's no similar federal requirement for individual gun owners.
What happens after a gun is stolen?

Proponents say reporting requirements, at their most basic, enable law enforcement to track down stolen guns faster—hopefully, before they're used in a crime. But the laws do more than that. As in the Connecticut case, they can also help to identify trends of suspicious purchases and "thefts" to suss out cases of straw purchasing and gun trafficking.
"That helps a lot in firearms trafficking cases and dealing with straw purchasers, who routinely use a gun being 'stolen' as their excuse," said Michael Bouchard, a former Bureau of Alcohol, Tobacco, Firearms and Explosives assistant director and president of the ATF Association.
Firearms stolen from private citizens account for nearly 95 percent of all guns stolen in thefts, according to a 2025 . From 2019 to 2023, nearly 1.1 million firearms were reported stolen, and more than 1 million of those were stolen from private citizens, or roughly 200,000 annually.
Once out of the hands of their original owners, those guns are to be used in crimes, according to research published last year in the journal Injury Epidemiology. For the study, the Violence Prevention Research Program at the University of California, Davis, analyzed over 8 million gun sales records and tens of thousands of reports of crime guns being recovered by law enforcement. They found that guns reported lost were three times more likely to be used in crimes. Stolen guns had nearly nine times the likelihood.
The researchers noted that guarding firearms against theft and loss should be a "primary focus" of efforts to prevent gun violence.
"If someone steals your gun, it's likely a gun thief is going to use it in a crime, probably against somebody," Bouchard said. "If an officer confronts someone with a firearm, and it's been reported stolen, now that's one crime gun that's taken off the street before there are any more victims."
In Minnesota, state Representative Kaohly Vang Her, a Democrat, has been trying to get a mandatory reporting requirement passed for several years.
"I own a gun. I've hunted probably for about 25 years," Her said. "It makes me feel more strongly that we need better gun violence prevention and about what it means to be a responsible gun owner. When I think about lost or stolen firearms, it's just common sense that this is what we should be doing."
Her's bill passed the Minnesota House during the state's 2023-2024 legislative session, but it ultimately failed in the upper chamber. She plans to file a new version in the coming weeks. Lawmakers in at least three other states—Texas, Missouri, and Kansas—have proposed similar bills, while legislators in Illinois and Ohio have proposed measures to strengthen existing requirements. The proposals come after the Biden administration released that states could follow.
In Congress, U.S. Representative Sean Casten, an Illinois Democrat, introduced on Feb. 21 that would require lost or stolen firearms to be reported to law enforcement within 48 hours. But it faces an uphill battle with Republicans in control.
Two sides to the coin

Republican lawmakers and gun rights groups frequently oppose reporting requirements as a burden on law-abiding gun owners.
"This bill creates criminal penalties for the victims of crime," Minnesota state Representative Walter Hudson, a Republican who opposed Her's bill, said during a committee hearing on the legislation. "What this seems to be targeting is lawful gun owners who do not make reports for reasons that are their own."
But proponents of the laws say the burden is minimal. The amount of time gun owners have to report a theft from 24 hours to a week, and there are typically exceptions if a gun owner didn't immediately realize their gun was stolen—like if, say, it went missing from a vacation home.
"This is not that hard. It doesn't burden anybody to report a gun as stolen," Bouchard said. "It's not just like I lost my wallet, or I lost a ring. A gun, if it's stolen, it's in a criminal's hands."
The effect of mandatory reporting laws on rates of gun violence been researched extensively, but have found them to be associated with reduced gun trafficking. of those studies, published in 2020, found that the laws may reduce trafficking to other states by as much as 28 percent.
"Failing to report a firearm stolen—that's an offense that takes away your opportunity to continue to be a straw purchaser, because you now have a criminal offense on your record, assuming you're caught," said Jim Burch, the president of the National Policing Institute and a former ATF acting assistant director.
Other policies could improve or build on reporting requirements.
Under Oregon's law, gun owners who fail to report the theft of their firearm can be sued if their gun is used in a crime. The risk of facing an expensive lawsuit could be a bigger incentive to report than the comparably smaller fines associated with most mandatory reporting laws.
Not all strategies need to be punitive. In Ohio and Florida, law enforcement maintains databases that allow gun purchasers to check if the gun they're looking to buy has been reported stolen. And in some states, "Save-a-Casing" programs provide gun owners with a way to give law enforcement spent shell casings that can connect stolen guns with crimes.
"It gives them much, much stronger potential for recovering firearms quickly," said Burch, who authored on reporting laws and how they could be improved.
Mandatory reporting requirements are far from a fix-all solution for gun violence. One major issue: The laws often go unenforced.
"The penalties for violating these laws are, in some cases, as low as $25 fines, so the effort that it takes to prosecute someone for that kind of a penalty kind of serves as a disincentive," Burch said. "I don't know that we see good evidence of how they're working, because I don't know that we've seen good evidence that they're actually being implemented and enforced."
Still, for Her, the Minnesota representative, the argument that reporting laws won't fix everything isn't a reason not to try.
"There is no piece of legislation that anybody writes in any state that is perfect," she said. "What I do know is that gun violence is an epidemic in this country. And if this helps prevent people from getting hurt, why wouldn't we?"
