Respectfully, if you are looking at from a non-legal perspective, you could conclude that he "had to have a reason." But under the law, imo, he did not. So, unless George did something else to Trayvon that amounted to a certain type of crime or threatened him with imminent bodily harm or death FIRST (which following him, in and of itself, was not), Trayvon's alleged physical assualt would be what triggers SYG at the moment GZ became fearful or serious injury or death. And that fear doesn't have to be based on Trayvon's actual ability to inflict such harm. GZ's fear just has to be reasonable under the circumstances. jmoo
I think the sticking point in the conversation is the idea that following, approaching or even confronting Trayvon verbally is illegal. It is not, imo. So that's the basis of my interpretation of how SYG will apply in this case
