Cops routinely kill people even when there's no reasonable way to claim they were in a "life threatening situation".
All this will do is make it easier for cops to kill people and evade accountability.
Robots are not going to solve the problem of people abusing the power they're given because they can. I'd argue that it would exacerbate it.
I don't see anything good coming from turning shooting real people into a video game for cops.
The main issue to my understanding is that you can't trust police reports as they have no incentive to write their motives plainly, and no peer pressure to expose bad reporting.
Yeah they stopped going on calls unless cops were present because they kept getting injured or used as hostages.
Please cite your sources (or any evidence at all) if you're going to make statements like that.
It seems you're proposing that the only sensible option is always more cops.
