DETROIT COPS RELEASE GRAPHIC SHOOTING VIDEO

THIS is the graphic footage of a gunman striding into a Detroit police station and blasting surprised Cops with shotgun.
It shows Lamar Moore, 38, walking into the precinct and past the building's raised front desk.
Pulling out the concealed weapon he sprays shells hitting a female sergeant in her bullet-proof vest. He's then seen firing more shots down the hallway as he reverses his steps back into the middle of the lobby.

Two other sergeants were down that hallway returning fire at Moore, Assistant Chief Chester Logan told reporters viewing the recording Friday at Detroit Police Headquarters.
The grainy surveillance video with muted color from Sunday's rampage at the 6th Precinct was made public only after members of the city's police force had seen it.

Cops have not determined a motive for Moore's rampage. The day after, his younger brother was sentenced to up to 60 years in prison for the shooting deaths last year of two men at a Detroit auto repair shop.

Investigators also were looking into allegations that Moore had kidnapped and sexually assaulted a 13-year-old girl in his northwest side home which we reported here.
He was not charged in the alleged rape.
