>far-right authoritarianism
Get a grip. Even if it were a reference to what you say it is, that has nothing to do with the "far right". It is stock standard centre-right (and centre-left for that matter) position in the US to support the police in principle (if not, obviously, in every action theyve ever taken). The "defund the police" types are a minority of a minority.
[0] how do you think police get so biased against everyone else to begin with? they're effectively dealing with the shittiest rungs of society on repeat, so they form a pattern and end up applying it to everyone they meet
So yes, to make it concrete and cut past the bullshit euphemisms, sometimes the police will shoot an "unarmed" black man. Sometimes, very rarely, the so-called "unarmed" person not only doesn't have a gun but doesn't pose a real threat to the life or limb of another person. That sucks. But we cannot get rid of those "type I errors" without curtailing the use of force in a way that produces more "type II errors" in the sense that the police don't use force in a scenario where they should have, and someone gets hurt unnecessarily by someone that should have been disarmed or killed by a policeman earlier.
That is in no sense a defence of those extremely rare cases where a policeman just murders someone and there is no justification or excuse.
It is not unreasonable for them to point out that if they are held to an impossible standard where they get blamed if they don't perfectly protect the public but they also get blamed if they ever have to make a split second decision with limited information, choose to use force, and it turns out not to have been necessary, that that impossible standard is not fair.
None of that has anything to do with "neofascism" or "authoritarianism", which are simply bogeymen invented by the left.
