When George Zimmerman shot and killed Trayvon Martin, he invoked a "Stand Your Ground" defense. And now, supporters of the law are finding themselves on the defensive.

Florida Matters host Carson Cooper breaks down what the Stand Your Ground law does and does not allow with two experts.

Stephen Romine is a Clearwater defense attorney who has successfully defended clients in several Stand Your Ground cases.
