Because it's an easy target. .If this idiot was in an institution like he should have been it would cost the state money. Strickter gun laws are not going to prevent this from happening again. This kid was known to be dangerous long before this tragedy. Now that this happened it's always the gun manufacturers fault, Get hit by a car it's the carmakers fault, Spill hot coffee on yourself ..... That's right blame McDonalds , The common denominator is money and not being responsible for your own actions.
