THIS IS THE KIND OF BULLSH!T THE NYPD BE ON! BEATS THE SH!T OUT OF SOME GUY FOR TALKING BACK TO THEM!

The partner of a city housing cop caught on videotape pummeling an Iraq war veteran testified Monday that the vet was aggressive throughout the encounter.

Walter Harvin - confronted by Officer David London as he tried to enter his mother's W. 93rd St. building without a key - hurled obscenities before, during and after the baton beating inflicted by London, Mohammed Khan said on the stand.

Harvin yelled "I'll kill you mother----er," and "I'll f--- you up" as London hit him repeatedly, Khan said. He also kicked the cop while on the ground, Khan said.

The video, released publicly for the first time yesterday, shows Harvin shoving London and the cop striking him again and again, continuing to smack the 28-year old and kick him after he was on the ground.

Harvin's uncle, Earl Jones, stormed out of court in disgust when the video was shown. "You don't beat a dog like that," Jones, 55, said. "The public should see it. They need to see so they can be aware how cops treat people."

London, 45, is on trial for assault and for falsifying the police report that claimed he was punched and kicked during the July 2008 confrontation.

"He didn't punch us," Khan, a 10-year police veteran facing departmental charges for not reporting the alleged abuse, testified.
