Extremist Wacko's

I'm really fed up. I just finished listening to the recently-released audio clips of that wacko UNC-CH student who ran over nine people in his SUV. (You can listen to it here.) What in the HELL is wrong with some of these people. Thankfully, some Islamic groups have already issued condemnations for the act... I wonder what (if anything) George Clooney or Sean Penn will have to say on the subject.
