The serious problem is that the US homicide rate is four times the rate of most Western European countries, Australia, New Zealand and Canada, and Eight times the rate of Switzerland where most have firearms and those that do are licensed.
This has nothing to do with paranoia/ignorance just looking at cold hard data available to all.
It has ALWAYS been higher in the US than in some other countries.
Never been any different.
The ONLY think you can confiscate to make a difference is all handguns, which is something like 85% to 90% of firearm homicides.
That ain't happening without overturning Heller and the 2nd Amendment.
I do encourage you to apply to emigrate to Canada or France or Germany though.
I think it's very important that you feel safe. And that's not going to happen here. So leave.
