It's not even the full story. Some of the other commenters are correct in that the gun problem in America isn't just about the laws or ability to change amendments. It's also about the American obsession with guns. We have the same obsession with guns recreationally that some war torn nations have with them who actually need them for defense.

The memes about like. Child soldiers in Sierra Leone or Iraq showing off gun stockpiles vs American family photos with 200 guns and 12 people in America isn't a one off thing. Our society has kind of been poisoned by guns as some kind of weird ideology. This has a lot to do with fear mongering and the gun lobby. But also with all our other systemic problems like poverty, and racism, and class warfare, and lack of universal healthcare and significant failures in even implementing mental healthcare that's accessible.

The idea that we can just throw some gun laws at the problem is crazy because all it's ever been is a bandaid.
