It's not just fear by officials of being shot (although that certainly is a factor, i.e police "no-go zones" controlled by gangs. As opposed to single unarmed minority motorists who can be bullied with impunity.).

It's also threat of public blowback from armed firefights leading to uncomfortable "why?" questions and detailed examinations of policies and the details of what happened.

Ass covering bureaucrats hate that. It could affect the pension.
