This makes me so mad to read this. Robert must have seen a lot of crazy shit in his time regarding over zealous fans. In this day and age, you have to be cautious of everything. Dimebag Darrell anyone?? I can't believe how stupid the venue security was there to not have done anything.
Edited: Just noticed that Cabal200 wrote something similar. Sorry, was just so mad that I didn't even read the responses after.
