I'm not saying that's WHY he was arrested, me and you don't know sh**t about whether he was breaking the law. All I'm offering is that it's quite likely he was doing it because he's done it before.
So every person who has ever committed a crime should be arrested because they've likely committed that crime again?
Garner's "fighting" basically amounted to him verbally arguing with the cops and waving his arms a few times. You're telling me he has no right to do either of those things when he's being arrested for a crime there's no evidence for?
Probably because he wasn't spotted by a messed up cop with a history of sadistic bullying. Also, given that he was actually guilty in the previous incidences his arresters presumably had some actual evidence.
