The Libs are already drooling over this, They will propose insane gun-grabbing. When the Repub House disagrees, the Repubs will be branded mass murderers in the 2014 election, with pictures of this shooting run 24/7. They will get and show photos of the dead kids lying on the floor. Might work unless Boner and Co. get off their asses.
I contend that it will only take the next Obama appointed Supreme Court Justice to wreck the Second Amendment.
