I do find it interesting that not one FReeper over the last two days has answered my question: What could Zimmerman have hoped to gain by getting out and looking for Martin (with police on the way, per the dispatcher)? No one will offer an answer.
Your question makes no difference. The fact that Zimmerman got out of his truck does not give the thug the right to beat the crap out of him. In fact, that is why Zimmerman was never charged, because a witness attested to this fact.
