So no "assault rifles" were used in the Tragic shooting in CT, and the shooter was not able to purchase an "assault rifle" because of laws on the books already. But this comes out AFTER they are banned in some states and EO's are signed to restrict the purchase of them.
So, people are trying to restrict something that wasn't used in the shooting. Lets ban all bicycles to prevent drunk driving. Here's an idea lets look at government spending instead.
