That i agree with, as it would prevent future incidences like this from happening again hopefully. But this guy should be trialed and held accountable, without a doubt. I personally believe he deserves nothing less than the death penalty, taking into consideration the pain he has caused to the families of the deceased(which a lot of you seem to disregard), and taking into consideration, the fact that it was completely unprovoked. If this was an Afghan man, who killed Western civilians, the whole world would be singing a different tune, he'd probably end up in Guantanamo, getting tortured and wishing they'd have killed him instead.
