Personally I'd go with "Reform the Police" or "Police the Police". Or maybe "De-Militarize the Police" which is not the only goal but one with broader support.

Just as a slogan, "Reform" is too boring and vague. "Police the police" is catchy but sounds more about oversight, which is not really the idea here. I thought of "Reduce the police", which might get broader support than "defund", but isn't as catchy and maybe still wouldn't get majority support. Polls show the police are still popular, though obviously and justifiably less popular lately. I suspect these calls for defunding (and abolition) are going to scare public opinion back in the other direction, which is a pity, since there really is a reform position to stake out here. For example, I bet even most police offers don't want to be the ones to have to deal with mental illness, addiction, and homelessness. A moderate and non-scary reform movement would surely get massive public support at this time, while a radical one is likely to provoke a counterreaction. It probably always works that way though, and eventually something comes out of it anyhow.

How about “Calm the Police” or “Calm 9-1-1”

Not energetic enough. How about "Replace the police"?

Maybe let BLM pick and setup their own police inspectors and have some oversight over an agency that polices the police. Instead of D.A. handling cop cases it would be members of this agency (they'd have lawyers who handle prosecutions - their own D.A.). Could be on a national or state by state level.

How would de-militarizing the police affect the overwhelming racism problem that exists in police departments nationwide?

Democrats are unlikely to do that. If de-unionizing police is solution to incompetent cops what is the solution to incompetent schools ?

I think most people do not see most teachers as the basic problem in public schools. E.g. polls show overwhelming support for paying teachers more. The same has been true of police, but less so - Maybe that's changed?

If people perceive most of the workers as the basic problem in addition to the management and the government, which they rarely do, but police may now be an exception, I don't see why the union should be spared.

The problem is that would lead to cognitive dissonance, as the people who want to defund the police also tend to be very pro-union.

I lean libertarian socialist. Big unionist, and I say fuck police unions. End them all.

This is worrying to many on the left, since it implies that unions could be bad. The ideologically consistent viewpoint is that the very concept of policing itself is so evil that it taints even associated unions.

Maybe we could reorganize the police as a private enforcement group that wouldn't answer to the courts or constitution?

Sort of like the brownshirts before WWII. [1]

Edit: Youtube took down a video of them back in 2019. [2]

That sounds like it goes in the opposite direction, we need police to have MORE not LESS oversight and be under more scrutiny and actually get punished (probably 2-3x the sentence of a non-officer).

And yet, the no-police zone in Seattle is just what I described.
