It is called suspicious activity and it is acceptable under community policing standards. Confronting him is not but it is legal.
The only thing that can convict Zimmerman is hard evidence, eyewitnesses or admission. Proponderance of evidence cannot as I understand it but reasonable doubt can set him free under our system and you keep missing that point or do not understand what it entails and I am beginning to think it is willingly to just argue with someone you dislike. Either way you are wrong. Do you really think a prosecutor is not aware of racial bias and that they would botch a possible murder case? Listen to yourself. They know a winning case and a loser and are not going to waste time on trying someone without a chance of winning and you are armchair quarterbacking to prove something that will never get beyond a grand jury. You may be right but I disagree and I think it is time to leave it at that.
I have no idea who it is you think I do not like. I do not know Zimmerman, so can have nothing personal against him. I am continuing to post because I feel strongly that race is a factor in this killing. You may not feel that it is, but that's your opinion. You can say what you want, and I can say what I want. "Suspicious activity" What would that be? walking while black?
