There ARE a lot of weirdos these days. And when you combine alcohol, hot women, and guys trying to get with the hot women, it's a pretty dangerous combination.
It hits especially close to home with the last two club shootings that I've heard about, are both clubs that I've been to. The recent one, Cheerleaders in Philly, is the club that actually got me additicted to the SC scene, and is a really fun club with a LOT of very attractive girls. The other shooting (the one with the Pacer player involvement) was at Club Rio in Indy. Been there, too, but didn't like it and wouldn't be back.
Kind'a scary, though. It shows that we can NEVER be too careful at clubs.
