But here's the thing. If Zimmerman had identified himself as neighborhood watch and he's not just some random white looking person (we know he's half Peruvian but if I'm in that situation I wouldn't know he wasn't just white, Trayvon probably didn't either), then I'm sure conflict is probably avoided. He NEVER mentioned he's with the watch or asked him if he was lost he assumes he's a criminal.
If he said "I'm neighborhood watch, we've had some breakins and you fit the profile, do you live here? Are you lost? Do you need help? Etc. don't make it sound like Trayvon is the only person who had choices here. I've never in my life interacted with a neighborhood watch volunteer who didn't have some kind of identification or let me know they were a part of that. The hell am I raising my hands and submitting to a random citizen who for all I know could be trying to rob or kill me especially after they followed me? Comparing it to police is a totally different case. They have a degree of authority, Zimmerman is a guy with a checkered past with a gun. Why was shooting the ONLY resort or option taken by him? You don't punch, kick, etc. in a confrontation? The LAST resort is using your firearm especially out in the open in a situation you created and escalated to another level by stepping out of your car. When all you should have done is call the police and let them do their job.
