This sucks and is terrible. I think that if the police would've investigated the guy a bit more on the Internet, they could've found out that he might be a real risk, but instead they let him keep his gun and next day we get this shit. I'm not really blaming the police because the guy apparently seemed like a normal guy, and it's really hard to even try to predict something terrible like this.
Anyway it's insane how fast the information about the incident spread on the net. Like the shooting started around 11am, and people knew who the shooter was like 10-15 mins from that on IRC (IRCnet anyway, where various finnish channels exist). I heard that somehow the name of the police who was questioning the guy on monday also leaked out and spread on IRC. Insane and scary...

big thanx to dragonslayer for sig!
