Looking at other countries, I can only conclude that America simply needs less guns in circulation but good luck putting the genie back in the bottle, people seem to revel in the antiquated "ULL NEVER TAKE MAH GUNS" type attitude. As if their personal firearm gives them any sway if the government actually wants to infringe on their rights.
No politician is going to realistically touch it other than lip service anyway.
