Insane cop delivers flying knee to back of 17-year-old’s head then threatens to kill him (VIDEO)

In the video, captured by Jordan Rojas, a friend of 17-year-old Andrew Rodriguez, we see an officer identified as "Officer Arnold" by the Dallas Observer (later identified by police as Officer Disraeli Arnold, a four and a half year veteran of the Hurst Police Department) sprinting towards Rodriguez and then slamming him in the back of the head with a flying knee.

After the brutal strike, Arnold screams, "Move, move, move and die! Move and fuckin’ die!"

"You wanna die here? Fuckin’ move again! Fuckin’ move again!" Arnold screamed.

Arnold then turns to the young man filming the incident and says, "Get up, get over here!"

Then, nonsensically, Arnold screams, "Stay down and shut the fuck up. Sit down and shut the fuck up! Don’t say nothing else!"

Moments later he screams at Rodrigquez, "Yeah faggot!"
