In Switzerland every male has a military type machine gun and two magazines at home and in my country, Austria, there are regions that rival Texas in terms of gun ownership.
Today I tend to believe that this might be a problem of city planning (and preventing ghettos). The US has cities that are much larger than the largest cities in the countries cited by me. But I might be wrong here.
Anyways, I do not doubt that police in Austria and Germany would act no differently than in the US if they had reason to expect that they could be shot every time they stopped a car. Thankfully this is not the case.
So solution is not remove guns, but remove "bad business". How to do that - different question. Legalization vs Extermination - yet to see which one is more efficient.
My point is that the mere availability of guns can't be the only reason.
This is most likely a very complex problem with many different issues that have to be tackled. Better police training, preventing ghettos, hopeless economic situation for people of certain race, racism - these are all issues that will have to be tackled to get this under control.
Just taking away the guns wont solve the problem I fear.
If you're insisting that the situation with firearms in Switzerland resembles that of the US you are either ignorant, obtuse, or dishonest. They are not even remotely comparable.
But it doesn't make any sense for me discuss anymore with you because you seem to believe that insulting others is a great way to exchange opinions.
