Yes, and conversely, NW IMO does not condone carrying a loaded gun while "Watching" nor does it recommend following and confronting someone you suspect of a crime. In fact, IMO, I don't think NW volunteers are taught to do anything other than report suspecious activity to police and then wait for LE to handle it. Certainly it does not recommend that you shoot and kill someone you have determined to be suspicious. IMO
Please post evidence Zimmerman confronted Trayvon. Surely if his intent was to confront, why not do if by the street where it was lit....why do it in a darken alley way behind houses. LE asked him for directions of where Tray was going....and Zimmerman attempted to do so. He did it for maybe a minute more than he needed to but again, not against the law, just poor judgement.
Poor judgement does not equal murder. Poor judgement....trying to beat a red light, etc. putting yourself in danger when it was not necessary.
