If guns can't prevent or stop crime then why are police armed?

The only logical conclusion based upon guns causing crime is that the police
are criminals.

Why does it bother you that people who live on the other side of the earth
own guns? Wouldn't it be more productive to worry about your wonderful
Muslim neighbors? Perhaps ChiCom imperialist expansion?

America has not invaded or taken over a country in more than 4 years so I
don't understand your concerns.
