This is exactly why we have the right to shoot and kill an unarmed person who breaks into our home. You do not have to wait to be attacked to defend yourself if a person has done things that a reasonable person would deem to be threatening. Following you around in the dark is pretty threatening. Add the confrontation and you have almost certainly crossed the threshold into committing assault.It depends on if you're cornering me for no reason. How you respond when I do or don't answer. If I say leave me alone or don't answer its very possible. Remember you as a citizen have no right to approach me demanding anything of me from where I'm going to what I'm doing there. If you continue to approach me I just might get physical. Again, that man has no right to demand anything of the kid and if Zimmerman doesn't leave him alone he has the right to try and make him. He already fled once and Zimmerman followed him. How many times is the kid obligated to run from this man before he can defend himself physically?
Florida law: Assault is defined as "an intentional threat by word, or act that seeks to physically harm another, coupled with an apparent ability to do so, which creates a well-founded fear in such other person that such violence is imminent."
