Zimmerman's trial may or may not have penalties for Zimmerman. An important decision might come from the occasion.
As of now, a person of prejudice can buy a gun, join a neighborhood watch, see a person he doesn't like, leave the car, confront the person and shoot him dead. It seems that's what Florida lawmakers will permit, maybe encourage.
The important point to consider is whether Florida legislators will require penalties if they find that a neighborhood watch, or any other person, will leave their car to shoot someone. If not, it's open season on the public.
