It's fearmongering.. and look ut, "sniper" rifles and "scatter guns" will be next. And while that sounds all warm and fuzzy to the soccer moms, you can bet these things will look a hell of a lot like your garden variety deer and duck guns.

WRONG! Then we just pare down again and begin anew with some other awful, horrible weapon that kills children, double parks, calls people at 3 in the morning to ask if the fridge is running, etc.
Because this is a scheme designed to progressively strip away weapons. If you don't believe that, then we will just disagree right here and save a few hundred posts on the matter.
