Even if they carry a loaded gun, they’re less likely to use it against the police than in the USA because punishments are less severe. In the extreme, three strikes laws (https://en.wikipedia.org/wiki/Three-strikes_law) makes even petty thieves with a previous felony conviction more likely to use a gun.

The USA has found a local optimum where cops have reason to be afraid of a large fraction of the population and vice versa, and doesn’t seem to be able to find a way out of it.
