Footage of two New York City police officers opening fire at a subway station as they confronted a man holding a knife shows they fired at him as he was standing still, his arms by his side and his back to a train.

A subway fare-beater accused of threatening a pair of NYPD officers with a knife, sparking a showdown that resulted in four being injured by police gunfire at a Brooklyn L station, was indicted Friday for assaulting the officer struck by his partner in the friendly fire shooting.

The NYPD released body camera footage showing the events leading up to a police-involved shooting at a Brooklyn subway station that injured a suspect, two bystanders and a police officer. The video was posted to the NYPD’s YouTube page on Friday.

The NYPD released Friday afternoon the body camera footage from the Brooklyn police-involved shooting almost one week after the incident left an officer wounded and a commuter suffering brain damage.

We are not perfect,” said John Chell, the Police Department’s chief of patrol, as protesters gathered in Union Square.

The 37-year-old man shot by police inside a Brooklyn subway station after allegedly wielding a knife pleaded not guilty to a litany of charges, including criminal assault, possession of a weapon and menacing.

A man who police shot on a crowded Brooklyn subway platform Sunday — after, the NYPD says, he skipped a fare and threatened officers with a knife — remains in a hospital bed and unable to walk, his attorney said Friday.
