In addition to what was already posted, I had read something that said that the club's exits were being blocked. WTF? You don't block exits to the building?

I've worked in clubs long enough to know that YOU DON'T SPRAY PEPPER SPRAY/MACE INTO THE CROWD. Stuff like that will cause mass hysteria. Normally when fights occur, the DJ's stops the music and all the lights are supposed to come on so people can see what's going on. Guards and staff are supposed to be trained to handle the situation without anyone getting hurt.

It's terrible to know that these club owners weren't supposed to even have this place open. It's so sad to hear that 21 people innocently lost their lives.
