Night clubs

It seems like you hear about an athlete being arrested at least once a week, and more often than not it occurs in a club.
Why are these guys still going to night clubs?
There are a ton of other things to do including sleeping and practicing for your sport. I just don;t understand why all of these guys have to keep going into these situations.

On a similar note, why do so many athletes have guns? I could see if somebody needed protection in their home, but it sounds like a lot of them carry their guns around with them.

They even take their guns into night clubs creating an even worse situation.
