The PROPER procedure is to tell them to leave because the are trespassing and if they refuse to call the police and have them removed. If they come back THEN they can be arrested.
And the proper procedure for Only (some) Black Lives Matter members to protest alleged police misconduct is to peacefully assemble rather than rioting and looting and killing
So drop the holier than thou attitude because blacks are not following the rules either
What rules? This isn't a game and it's obvious you have no idea what you're talking about because what the hell does Black Lives Matter and the protestors have to do with these cretins physically assaulting this young man and claiming they were going to lynch him?
As far as my attitude, yeah heads and shoulders above a person you, a racist who was practically jumping up & down in glee when two protestors in Seattle were run down by a vehicle going the wrong way on I-5 which was blocked to vehicle traffic. The driver killed one of them and seriously injuryed the other. That puts you down below the racist clowns in this video/story, right there in the pig stye - fat, dumb & happy wallowing in the pig shit.
