There are about 55 million gun owners with 300 million guns in the US. Even private gun ownership were banned tomorrow, and 97% of gun owners could be threatened, bribed, or indoctrinated into giving up their firearms peacefully, 1.65 million gun owners would remain. There are just over 800,000 law enforcement officers in the entire country. The logistics of launching 1.65 million investigations, obtaining 1.65 million search warrants, launching 1.65 million SWAT raids, making 1.65 million arrests, and finding 20 million jurors willing to convict are staggering. It would cost an immense amount of time, money, and lives.
