Just political pandering. Fact is, none of those kids have any idea what is going on, nor do they have clue one as to how to go about keeping psychos out of their schools with guns.
Guns are nothing more than a death delivery device. Not even the best, or most efficient one, at that. For my money, I'll wager a good roaring gasoline fire would have had a higher body count at Sandy Hook, than even an unlimited supply of .223 rounds in his AR-15. Or poison. I mean, think about what would happen if someone with half a brain were to get their hands on some of the boxes coming off of the City Line/Sysco truck, as it made it's daily/weekly delivery of food to the school cafeteria? A little rat poison goes a long way, you know?
Fact of the matter is, no matter WHAT the president does about guns, it's NOT going to help the situation we currently have.
