Police Officer To Cameraman In Ferguson: 'I Will F---ing Kill You'

A police officer in Ferguson, Missouri apparently threatened a man who was filming him and responded "go f--- yourself" when asked his name.

The police officer in the YouTube video so far hasn't been identified. The video was reportedly filmed during protests Tuesday night.

An officer with a raised rifle was apparently attempting to disperse a crowd, repeatedly shouting "get back."

When a man behind the camera saw the cop, he said: "My hands are up, bro. My hands are up."

Others in the crowd then noted that the cop was pointing his gun at civilians.

The cop responded: "I will f---ing kill you. Get back."

A man behind the camera asked the officer his name. The officer apparently replied: "Go f--- yourself."

The American Civil Liberties Union of Missouri sent a letter to the State Highway Patrol asking that they "identify and remove" the officer in the video.

The letter reads, in part:

We understand that the situation in Ferguson has tense moments and that other officers appear to have intervened to diffuse the situation. However, this officer's conduct - from pointing a weapon, to threatening to kill, to responding with profanity to a request for identity - was from start to finish wholly unacceptable. Such behavior serves to heighten, not reduce, tension.

Protests broke out in Ferguson, a suburb of St. Louis, after a police officer shot and killed unarmed teenager Michael Brown. The officer stopped Brown and a friend for walking in the middle of the street.
