We are talking about a guy that has a history of beating his wife, sexually abusing his cousin, assaulting a police officer, and calling 911 almost 50 times in (what?) six months over stupid shit like trash in the road. Despite living in the community he was "patroling" as a busybody everyday, he could not give the operator the exact address where he was. Profiling a kid that he didn't even know and had not seen commit any crime and deciding to pursue him.
Does this sound like the actions of a sane man that wasn't seeking a conflict of some kind?
Really, what's the excuse going to be when he is found guilty?
