Years ago when I started doing TV and making appearances in big arenas, the place would put security guys up there and I said, "Please don't do that. It's very distracting to see ten cops in front of the stage. Everybody's looking at the officers instead of me. I don't want that." I also found that people will dare to break a barricade. If they have a barricade, somebody will always try to jump over it. I've found that the more open I am, the better.
