Dont know if youve been to the US or know anyone here personally but guns are not as prevalent as you might think. Theyre definitely “around” but id imagine many people could go their whole life without seeing one. Obviously you have states like texas where they have an open carry day, You can see people walking around with rifles and ARs. But not including police officers, and millitary personel. I just dont see them. Your paranoia is justafied tho, we definitely see the worst of humanity often enough.
