I followed the George Zimmerman trial fairly closely. Let me see if I understand the situation correctly.
* Zimmerman's neighborhood was subjected to numerous robberies and break-ins for several years. As a result, the neighborhood decided to form a Neighborhood Watch.
* While on watch one night, Zimmerman encountered an unknown person walking through the neighborhood. Zimmerman called the police to report this and the dispatcher told him to stay in the car. Nevertheless, Zimmerman got out of his car to observe what the person (Trayvon Martin) was doing.
* At some point, Martin confronted Zimmerman. He punched Zimmerman, breaking his nose and knocking him to the ground, then repeatedly slammed Zimmerman's head on the pavement.
* Fearing for his life, Zimmerman shot Martin (with his legally carried weapon).
If this is an accurate summary, it surprises me that those who say that Martin was murdered conveniently ignore the fact that Martin precipitated the physical confrontation. Martin could have just walked home, but instead, he chose to attack Zimmerman. I guess Zimmerman could have just lay on the ground and permitted Martin to beat him to death.
I don't have any idea why Martin decided to attack Zimmerman. Maybe it was the "attitude problem" Steve Rynders wrote about in his recent letter. I can't help but think Martin bears considerable responsibility for what happened.
