Personally, I think ammunition and firearm manufactureres should cease selling anything but revolvers and .38 ammo to the police and cease supplying wholesalers/retailers who do. After all, no one “needs” more.
You know, that’s not a bad idea. If the government is threatening gun ownership then a great protest would be for gun companies to refuse to sell any more arms or ammunition to government agencies. Starve the beast and its ability to do harm to its citizens.
