As a people we want what we can't have either by perception or reality. If the talk is to ban black guns then lets run out and buy two because we can today but maybe not in the future. It applies to ammo shortages as well, 22LR is hard to find so buy it wherever and as often as you can even if you don't use it, same with 45ACP, 9mm pick a caliber. Reloading brass is hard to find and I'm always ;looking for something, right now it's 500 N.E. 3" cases but it's always going to be something.
By nature we are hoarders. It's better to have it and not need it than to need it and not have it
