A huge different than the previous night it was. Basically a peaceful like there were few problems there were.

The police were there there were no confrontation. No tear -- no Molotov cocktails. Apparently the -- and -- -- and before one bottle throwing early in the evening it would it would essentially people marching. People going home without any problems so it is a huge different than a officials are hoping that really marks the change in in the attitude that the marchers have during the demonstrations in treatments. Shave what is media making a guest today is visit to Ferguson by US attorney general Eric Holder did his visit do anything two. You know helpful calm down the situation. You know I don't think it really and that's certainly affected last night's. Demonstration for you I don't think the protesters are waiting to.
