The scoop in this story goes to The Sunday Star-Ledger which first disclosed the State Police video. It was only after the Star-Ledger told the police that it was going public that the police department acknowledged publicly that the officer used excessive force.
The troopers were reportedly Staff Sgt. Richard Wambold Jr. and Trooper Keith Juckett who are shown stopping Bayliss at a blockade set up to catch burglary suspects. Bayliss is seen standing against the car as Wambold frisks him. A few seconds later, Wambold throws him to the ground and starts to pummel him. Witnesses say that the officers then dragged Bayliss across the ground, handcuffed him, and then rammed his head against a tire.
