Unfortunately, the US is not Europe. There are already millions of guns in circulation, and a relatively porous border to the south through which enormous volumes of smuggling routinely take place. Even if you were able to muster support for a blanket ban on firearms, you would need to propose a credible means through which to recover the guns in circulation and prevent their replacement through illegal traffic.

It would behoove your analysis to consider American gun legislation through this lens. It might even prompt an original thought.
