The problem is if you look at murder rates (drop the word "gun" from "murder rates"), the USA is way down the list with the gun banning countries higher up (they just use knives, bats, bombs instead of guns).
I've seen people wondering why the government is doing things to convince people to buy more guns. Part is explained by mental illness of the leaders (for example, a certain anti-gun politician from our state has obvious PTSD as she keeps bringing up a murder she walked in on many years ago). I don't know about the rest. Many actions of our government appear to be those of someone trapped and in a panic, maybe that's it, they see their own demise and can't abide that. Whatever it is, I know it's pushed people I know to start arming themselves when they would otherwise never have bothered.
