Its because I am not a kunt.
Tons of doormen over here beat people up week in week out why would I do the same when I can get the job done by using my mouth 99% of the time?
Also you are saying that the cop only done that because the guy was handcuffed, the cop had a gun and because he knew this and thought he would act a bully?
Thing is they guy in the video will prob get a large payout and be glad the cop done it.
