An ICE agent fatally shot a Minneapolis woman during an immigration enforcement operation Wednesday, reviving a debate over when law enforcement officers may legally use lethal force against someone in a moving vehicle. The woman, identified by family members as Renee Nicole Good, 37, died after being shot in a confrontation captured on cellphone video. The killing drew immediate and conflicting responses from federal authorities, who defended the agent’s actions, and local officials, who questioned whether deadly force was justified.

The shooting exposed sharp divisions over federal use-of-force guidelines that generally bar officers from firing at vehicles unless the driver poses an imminent threat beyond the vehicle itself — policies many police departments adopted decades ago to reduce risks to bystanders and to drivers who may lose control after being shot.

Federal officials defend the agent

Homeland Security Secretary Kristi Noem, speaking at a news conference Wednesday, described the episode as an “act of domestic terrorism” and said the agent acted in self-defense.

“Our officer followed his training, did exactly what he’s been taught to do in that situation, and took actions to defend himself and defend his fellow law enforcement officers,” Noem said.

Noem alleged that Good had been using her vehicle to block officers, had been harassing them through the day, and “attempted to run a law enforcement officer over” before she was shot. Noem said the FBI is leading the investigation.

What federal policy requires

Federal law enforcement officers operate under Department of Justice guidance that says firearms should not be used simply to disable a moving vehicle. The policy allows deadly force only in limited circumstances — such as when someone in the vehicle is threatening another person with deadly force, or when the vehicle itself poses an imminent risk and no reasonable alternative exists, including moving out of the vehicle’s path.

The shooting occurred as Homeland Security escalated immigration enforcement in Minnesota by deploying 2,000 agents and officers. It is at least the fifth fatality in violent encounters between ICE agents and community members, according to the Associated Press.

Experts call for parallel investigations

Geoffrey Alpert, a criminology professor at the University of South Carolina, urged caution before drawing conclusions.

“There needs to be two thorough parallel investigations,” Alpert said. “First ICE officials should investigate administratively whether this agent violated policy or training. And then state officials should be conducting a thorough criminal investigation as well.”

Alpert said determining whether the use of force was justified or criminal would depend on many details not yet disclosed publicly.

John P. Gross, a professor at the University of Wisconsin School of Law who has written extensively about officers shooting at moving vehicles, was more pointed in his assessment.

“If this woman was blocking the street and a law enforcement operation, they are entitled to arrest her. What they are not entitled to do is to use deadly force to arrest her,” Gross said. “From just watching the video, this seems like an egregious example.”

Gross said officers must consider the totality of a situation — the crime or allegation at issue, whether a person can be located at a later date, and whether they pose an actual danger. He noted that Minnesota has revised its use-of-force statutes to require clearly identified and immediate threats, and to make it easier for prosecutors to file state charges for excessive force.

Whether charges are possible

It is too early to know whether the ICE officer could face criminal charges. Multiple investigations are ongoing, and prosecutors have said no decisions will be made until those inquiries are complete.

Daniel Borgertpoepping, a spokesperson for the Hennepin County Attorney’s Office, said investigators are still gathering facts. “The bottom line is yes, we have jurisdiction,” he said, adding that charging decisions would come later, if at all.

Federal law enforcement officers have broad legal protections when acting in the course of their official duties. Late last year, Deputy Attorney General Todd Blanche said arrests of federal officers performing their duties would be “illegal and futile,” citing the Constitution’s Supremacy Clause and federal law. Legal experts said those protections are significant but not absolute — federal agents can still face criminal liability if prosecutors determine they acted unlawfully or outside their authority.

A pattern of contested incidents

The Minneapolis case is not the first to draw scrutiny. In October, a Chicago woman, Marimar Martinez, 30, was shot five times by a Border Patrol agent in a similar incident involving a vehicle. Homeland Security officials called her a “domestic terrorist” and said she had ambushed and rammed agents with her vehicle. She was charged with assaulting a federal officer.

Federal prosecutors later dismissed the case after security camera video and body camera footage showed a Border Patrol agent steering his vehicle into Martinez’s truck.

In Wednesday’s Minneapolis shooting, the vehicle can be seen in video crashing into two parked cars before coming to a stop. It was unclear from the video whether the vehicle made contact with the officer before he stepped to the side.

How moving-vehicle policies developed

Law enforcement agencies have restricted shooting at moving vehicles for decades, citing the danger to bystanders and the risk that a driver who is shot will lose control.

The New York City Police Department was among the first to adopt such limits, barring officers from firing at or from moving vehicles after a 1972 shooting killed a 10-year-old passenger in a stolen car and sparked protests. Research in subsequent years found the policy, along with other use-of-force restrictions, helped reduce bystander injuries and deaths in police shootings.

The Police Executive Research Forum and the International Association of Chiefs of Police have recommended similar limits, warning that shooting at vehicles creates serious risks from stray gunfire or from a vehicle crashing if the driver is hit.
