The vast majority of interactions with the public can be taken care of with non-lethal means, tasers, etc… (if any are even necessary).
Lethal weapons should be in a remote lock holster in their cruiser, and must be unlocked remotely by a supervisor on a per-case basis depending on the facts at hand (suspect’s history, potential risk, etc…)
Maybe that’s pie in the sky optimism, I don’t know.
The fascist dystopia of watchmen allowed cops to be completely anonymous for their safety, but still restricted officers access to firearms. We’ve blown past the parody at this point.
