The problem is the supreme court already struck down a handgun ban. It also "probably' struck down a ban on AR-15's and the new ban in NY on 10 round magazines with the whole common use situation but they weren’t quite clear enough so sounds like we will see another round of fights over that.
The president said it himself before, the "problem" is "cheap available handguns".
Honestly I think the Sheriff from San Diego said it best yesterday, they want to disarm us totally. Every single gun, even if it takes a generation. As long as you or I can own so much as a hunting rifle it will not be enough.
