Whenever anything like this happens its a sad event of course, but fortunately it sounds like he was as much of a bad shot as he was an idiot so there weren't as many fatalaties as there might have been, though not to take away from the fact that one person is dead and other seriously injured. I am rather shocked too to hear that there is a video game based on the Columbine massacre

is that really true?
I will say though, not to condone actions like this, but just because people dress in black and are 'different' it doesn't mean we should call the police and such as this person recommends, no more than you'd suspect every young muslim man of being a terrorist or every blonde of being an idiot etc
