5 people(i think) were trampled to death at an ac/dc cocert this decade i saw it on Vh1 Behind the Music 2 weeks ago. the security wouldn't open the doors of the stadium or whatever they were playing at. And they were inside practicing and warming up and the people outside waiting thought the concert had already started so they started pushing to get in but the security didn't give the okay for them to start letting people in so people were being crushed against the doors and stuff.
