On Sunday, leaders from law enforcement circles voiced their unease over the latest fatal shooting involving federal officers in Minneapolis. At the same time, experts in use-of-force challenged the Trump administration’s explanation of the event, citing discrepancies between the official narrative and what was captured on video by witnesses.

The federal authorities are also under fire for not initiating a civil rights investigation through the U.S. Justice Department and for their attempts to prevent Minnesota officials from conducting an independent review of the incident that resulted in the death of 37-year-old Alex Pretti.

In an effort to calm the situation, the International Association of Chiefs of Police has urged the White House to organize discussions “as soon as practicable” involving federal, state, and local law enforcement agencies.

“Police chiefs across the nation are closely monitoring the developments in Minneapolis,” stated Chuck Wexler, executive director of the Police Executive Research Forum, an organization dedicated to police research and policy. “If a police chief faced three officer-related shootings within three weeks, it would prompt a reassessment of training and policy protocols.”

The incident involving Pretti follows the January 7 shooting death of Renee Good and another episode a week later, where a federal officer shot a man in the leg during an arrest attempt after the officer was attacked with a shovel and broom handle by someone trying to assist a Venezuelan man in the country without legal documentation.

“We’re dealing with a federal agency here,” Wexler said, referring to the Department of Homeland Security, “but its actions can have a ripple effect across the entire country.”

While questions remained about the latest confrontation, use-of-force experts told The Associated Press that bystander video undermined federal authorities’ claim that Pretti “approached” a group of lawmen with a firearm and that a Border Patrol officer opened fire “defensively.” There has been no evidence made public, they said, that supports a claim by Border Patrol senior official Greg Bovino that Pretti, who had a permit to carry a concealed handgun, intended to “massacre law enforcement.”

“It’s very baked into the culture of American policing to not criticize other law enforcement agencies,” said Seth Stoughton, a former police officer and use-of-force expert who testified for prosecutors in the trial of the Minneapolis officer convicted of murdering George Floyd.

“But behind the scenes, there is nothing but professional scorn for the way that DHS is handling the aftermath of these incidents,” Stoughton said.

Several government officials had essentially convicted Pretti on social media before the crime scene had been processed.

Deputy White House chief of staff Stephen Miller generated outrage by describing Pretti as “a would-be assassin” in a post, while a top federal prosecutor in Los Angeles, Bill Essayli, drew the ire of the National Rifle Association for posting that “if you approach law enforcement with a gun, there is a high likelihood they will be legally justified in shooting you.”

“In a country that has more guns than people, the mere possession of a weapon does not establish an imminent threat to officers — and neither does having a weapon and approaching officers,” Stoughton said. “I don’t think there’s any evidence to confirm the official narrative at all. It’s not unlawful for someone to carry a weapon in Minnesota.”

In the hours after Pretti’s shooting, Minnesota authorities obtained a search warrant granting them access to the shooting scene. Drew Evans, superintendent for the Minnesota Bureau of Criminal Apprehension, said his team was blocked from the scene.

Minnesota authorities also received an emergency court order from a federal judge barring officials “from destroying or altering evidence related to the fatal shooting involving federal officers.”

Bovino sounded a less strident tone at a Sunday news conference, calling Pretti’s shooting a “tragedy that was preventable” even as he urged people not to “interfere, obstruct, delay or assault law enforcement.” He refused to comment on what he called the “freeze-frame concept,” referring to videos circulating on social media that raise doubts about the dangers Pretti posed to officers.

“That, folks, is why we have something called an investigation,” Bovino said. “I wasn’t there wrestling him myself. So I’m not going to speculate. I’m going to wait for that investigation.”

Policing experts said the irregularities in the federal response went beyond the government’s immediate defense. Before Pretti’s parents had even been notified of his death, DHS posted a photograph on X of a 9mm Sig Sauer semiautomatic handgun seized during the scuffle, portraying the weapon as justification for the killing.

“The suspect also had 2 magazines and no ID,” the post said. “This looks like a situation where an individual wanted to do maximum damage.”

However, the photo showed only one loaded magazine lying next to the pistol, which had apparently been emptied and displayed on the seat of a vehicle. Minnesota state officials said that, by removing the weapon from the scene, Border Patrol officers likely mishandled key evidence.

None of the half-dozen bystander videos shows Pretti brandishing his gun. Rather, the videos showed Pretti’s hands were only holding his mobile phone as a masked Border Patrol officer opened fire.

In videos of the scuffle, “gun, gun” is heard, and an officer appears to pull a handgun from Pretti’s waist area and begins moving away. As that happens, a first shot is fired by a Border Patrol officer. There’s a slight pause, and then the same officer fires several more times into Pretti’s back.

Several use-of-force experts said that unenhanced video clips alone would neither exonerate nor support prosecution of the officers, underscoring the need for a thorough investigation. A key piece of evidence will likely be the video from the phone Pretti was holding when he was killed. Federal officials have not yet released that footage or shared it with state investigators.

“The evaluation of the reasonableness of this shooting will entirely depend on when the pistol became visible and how, if at all, it was being displayed or used,” said Charles “Joe” Key, a former police lieutenant and longtime use-of-force expert.

Ian Adams, an assistant professor of criminal justice at the University of South Carolina, described the federal government’s response as “amateur hour.”

“Jumping to the end result of this investigation, or what’s supposed to be an investigation, is somewhat embarrassing for policing professionals nationwide,” Adams said. “It’s clear that professionals in policing are observing what’s going on and not liking what they’re seeing.”
