If you watch Good Morning America or the Today show or any of the national TV morning shows you see a lot of live crowd shots right behind the studio hosts. Obviously the areas around those broadcasts are secured from traffic and those who might act the donkey on live TV.

Sometimes despite their best efforts, those that report the news become the news. This is footage from WLS-TV in Chicago. It appears to be just a normal nighttime newscast when suddenly there is a loud noise. That noise happens to be a vehicle that has been driven right into the studio. at :26 seconds into the video the face of the news anchor is absolutely priceless.
