there are about 30 states that have stand your ground laws. this is a state issue, not a federal issue and you can talk about it and say you don't think they're good. there are studies that show they may cause more homicides, you can use that and bring it into the national conversation which is exactly what he did because what he didn't say in that speech yesterday, kate, was that they were going to bring civil rights charges. >> right. >> side stepped that saying there is an open investigation. >> he talked very passionately about the issue but he did not give an update if it was going to happen, only that there was an investigation. what's going on behind the scenes? >> i think in talking to people inside and outside the justice department what i've been told there's a high bar for the justice department to do this. you would actually have to prove intent, that zimmerman shot trayvon martin because he was black. that's very difficult. that was not a part of the case and so what they're going to do is they're going to be debriefing the prosecution, they're going to try and find evidence that maybe wasn't used
