Nicholas Brendon, who played Xander on Buffy the Vampire Slayer (and who recently dated a good friend of mine for a second) was arrested last night in Venice, California. He was drunkenly causing a commotion, took a swing at the cops and then was tasered!
Unfortunately, I think this is Nicky hitting rock bottom. Based on what I've been told about him, this is an ongoing problem, so I hope this leads to him actually getting the help he clearly needs. I wish him the best of luck, and hopefully an upswing in his career once he's better!
