Zimmerman not guilty.

[Xiahou]

Sounds like CinC is saying that if Martin had a gun, he should have shot Zimmerman rather than punching him, according to Florida Law.

If Zimmerman hadn't been beaten bloody, claiming self-defense would have been a lot more challenging.
If Martin shot Zimmerman just for following him, without a scratch on him... he'd likely go to prison.

It's a stupid and unhelpful comment from the president.
