There is one solution that bypasses politics, bureaucracy, or having to assign people to protect things: let people have reasonable access to firearms and legal recourse in their use to defend themselves and property.
The vast majority of people are normal, decent human beings that won't resort to shooting each other at every argument. The rest would probably pursue deadly force even if they didn't have access to firearms. Yes, US has a disproportionally a larger number of those due to our culture, but the way to fix that is to let former people arm themselves and the problem will be minimized.
