I agree with what you say, I just think it will be a lot harder for the feds to try Zimmerman the way they did with the LA cops. The case could make them look stupid. Feds really hate to look stupid. That doesn’t mean they can’t make life hell for Zimmerman, they can. But he should win in the end, especially with a federal jury. The feds might try to get a plea to a far lower offense and use their coercive power to get Zimmerman to give in. But I don’t see how they do any better than the state on the facts. As I said, you have an innocent man here, not a case that could go either way.
The L.A. cops in the Rodney King situation not only had evidence of abuse (although they were swinging the clubs to break bone - leg and arm - because their previous training to put it across the neck resulted in a death), but cops using racial pejoritives, not taking King to the hospital for a substantial period of time, etc.
