Police have released horrifying footage of a 25-year-old law student sitting in his car before he is killed in a hail of bullets after being shot by five officers.
Chase Allan, 25, was armed when he was killed on March 1 after being pulled over in Farmington, Utah, US, for allegedly having illegitimate licence plates.
Moments before gunfire erupted, one of the officers tells the student: "The direction this encounter goes is 100% in your hands."
Reports suggest Allan was a believer in the 'Sovereign Citizens' movement, who do no not believe they are bound by government laws.
In the video, Allan can be heard telling one officer: "I am not giving you jurisdiction. Do not detain. You are not allowed to stop me."
He refused to give his licence or even provide his name.
The officers had followed Allan's car into a post office parking lot.
Eventually Allan provided a passport but refused to exit his vehicle.
A second officer then threatens to break Allan's window. Throughout the young man is recording the encounter on his phone.
Seconds before gunfire erupted, Allan swapped the hand his phone was in, freeing up the one nearer a hip holster under his jacket.
When police eventually manage to get the car door open, Allan can be seen moving.
One officer suddenly yells: "Gun, gun, gun, gun, gun!"
Then the shooting starts during which 12 bullets were fired by the officers.
Allan's handgun was found in the car footwell next to the driver's seat and police say he was reaching for it.
Speaking to reporters, Farmington Police Chief Eric Johnsen acknowledged the body-worn camera footage was unclear about what happens just before the shooting as the struggle begins.
His family have called the incident "brutal murder".
His mum Diane said she thought her son was "terrified for her safety" during the traffic stop.
The police department have not claimed Allan fired any shots.
Farmington Police later released photos showing a handgun found on the floor of the car.
The Sovereign Citizen Movement claims individuals can refuse to accept the sovreignty of the wider state.
Photos of the vehicle after the incident show a flag sticker with the phrase "Utah, American State Citizen".
