You do have a right to confront anyone you choose, but that person also has a right to react based on how they perceive the confrontation. It is not against the law, per se, to follow (or CHASE) anyone, but it does have the potential to create a hostile situation. It's aggravating, and if you are pursuing someone, you are the aggressor. Under no circumstance is someone who is running AWAY posing an active threat to a person who is following them. I'd have to double check, but I don't even think police officers can use deadly force on a fleeing felon. This situation, in my opinion, is not a series of events as some like to portray it. It's one continuous occurrence; from the time GZ got out of his car and started following Trayvon, he was the aggressor.
Like fruits from a bad tree, GZ cannot be the pursuer, the chaser, the follower, the aggressor up until the actual confrontation happens. That makes no sense. He initiated the confrontation. Trayvon had no reason to approach him, he wasn't the one who had deemed someone suspicious and decided that the person would not get away.
I don't think any lawyer would go into court and say "sure, my client was following the victim, but the victim completely overreacted and became aggressive." That's what's being argued on this forum. It's completely flawed logic IMO.
Most reasonable people don't follow people who they deem to be "suspicious", and most reasonable people would be fearful if a stranger was following them. Jurors are reasonable people.
JMO MOO IMO
