As if the little punk walked into his local gun store and bought one legally off the shelf. It implies that if he couldn't have obtained such a weapon, he wouldn't have been able to kill so many.
But again sense succeeds where emotion fails, 1) because the kid murdered his mom to get the weapon, he didn't buy it legally, and 2) is murdering Only 10 or 15 innocent children with a different type of firearm really less tragic and more palatable than murdering 20?
But what speaks loudest against the gun grabbers are the facts about crime rates.
The crime rates in cities with the toughest gun controls laws like Chicago, Detroit, Washington DC, etc when compared to crime rates in CCW states.
