Do you honestly believe that guy in the video getting his a$$ kicked looks like a threat to 5 cops that are standing over him?
Any person with half an ounce of objectivity know these cops were out of line. They should all lose their jobs at the very least.
And you would want to be the cop trying to secure the guy's legs with shackles? Do you value your teeth? A handcuffed drunk can still let loose a nasty kick. Which is why the cops wanted him on his belly in the first place.
