 Still don't really know all of the nuts and bolts as to what happened. It doesn't appear that this was a direct attack on the RNC. I mean, homeless dudes with knives have been known to cause trouble. Well, I'll just play part of the report for you because I found this part to be interesting. George, Milwaukee, we know on high alert surrounding the RNC. Chief National Correspondent Matt Gutman is there with details on how police shot and killed a man near the arena. Good morning, Matt.
