Drugs, Shop-lifting, DUI, Robbery (unarmed), Prostitution, Protesting, etc...
We have tech to monitor ppl wherever they go, we could easily monitor these people w/ ankle bracelets etc and make sure they're behaving. We could require them to go to therapy and figure out the root of why they do what they do, you know what you'd do w/ a child who's acting out and misbehaving....
Maybe we curtail a lot of issues.... Save prison for pedophiles, rapists, murderers, assaults, etc....
A minority has had outsize political influence in the US for a decade or two now. Because of the electoral college and because of gerrymandering.
And the way in which the Electoral college disempowers lots of people (a vote in an 8 million person city counts less than one in Ohio, or a small town in Wisconsin) is easily verifiable.
One might disagree with ethical implications which can be drawn from these facts, but, these facts are facts, and there's even math to back it up.

Contrast that with "defund the police", the goals of which are amorphous even from its supporters, and if you don't think calls to defund the police are met with stares and questions like "are you insane" in any place besides mid-to-large urban areas in the US, you really need to pop your social bubble.
For better or for worse in a democracy you need to convince the majority (or near majority) of the population over to your side. The slogan "defund the police" is not the way to do it.
