came down we all watched the reaction across the country. This map tells the tale, thousands showing their support for trayvon martin in the streets from baltimore to atlanta, from new york to miami, the vast majority peaceful, something requested by trayvon martin's parents as the attorney for his family said in order for trayvon to rest in peace, we must all be peaceful. And now I want to bring in abc's chief legal analyst, night light anchor dan abrams. What caught your attention about what they say. What does he do now? We've seen this in some of the acquittals where some of the public is angry, o.J. Simpson, casey anthony. They have difficulty figuring out how to move on. The difference is george zimmerman has supporters. We saw today attorney general eric holder say that he's continuing his investigation into any civil rights violation. He was addressing all of the people who have been out on the streets. The justice department shares your concerns. I share your concerns. At the same time, of course he said it must be addressed with understanding and with truth. Is this the next thing to watch? I think it's very unlikely. They would have the same hurdles they had in the state case. They would then have to show it was motivated by race. More likely it's a civil lawsuit where the family would sue george zimmerman. There george zimmerman would have to testify. The standard would be lower. The problem there is if that happened the defense would go after trayvon martin in a way that they weren't able to in the criminal case. You could also see the defense team trying to win attorneys fees and other costs. There are definitely risksed. It's not necessarily going to happen. Sure. You've been answering questions for us from the beginning. I want anyone at home to know where grateful for the questions that you send us. Dan is going to tackle them all at abcnews.Com.
