Their mask will no doubt protect them from the bear spray, you know, because it also protects against viruses.

Seriously though, there is a non aggression principle, but like everything else, there needs to be a great questioning of the laws they enforce. Cops enforcing mask mandates, vaccine passports? Or cops protecting groups allowed to peacefully assemble to protest things others disagree with. My guess is you only want cops enforcing causes you believe in like protesting the color orange.
