Once I was in a situation similar to the one Trayvon Martin was in. At about 10:00 pm on a weeknight I was riding my bicycle past an office building I had years earlier guarded as a security guard. Because I am retroactive, I rode my bicycle to the parking lot. Two security guards came out to look at me. I got off of my bicycle, and walked with it to where the security guards were. "Excuse me," I began politely. "Am I trespassing?"
When I was told I was, I apologized, and said I would leave immediately. We had a brief, friendly conversation, and I left.
That is the way a civilized man behaves. Like those security guards, George Zimmerman was doing his job. All Trayvon Martin had to do was to walk over to Zimmerman, identify himself, and explain that he was staying with his father, who lived in the gated community. Instead, he attacked Zimmerman from behind, and began hitting him in the face.
