I agree with him. It's needlessly shockingly and doesn't really describe what people want.
Reform the police.
Fix the police.
There are countless better slogans to use.
Yeah, there was some article not too long ago shared on here that things like defund the police, all cops are bad helped galvanize conservatives in some states. Like the slogans are used to point out good points.
Funds need to be distributed in ways which means other services are available so police aren't needed and so that they can't pay off lawsuits with no consequence, and so there are less police who are of higher quality. That's what I take away from defund the police, but others see it as "no more police"
ACAB means to me that policing can't be good if police units allow bad cops to operate freely and with no consequence. Others see it as all cops are killers and thugs in a uniform.
You can see how you lose voters with slogans like those. At the same time, they bring awareness and discussion. But at the same time, it wasn't that long ago Black Lives Matter was viewed as something that was exclusionary and now is accepted as a message that black people don't get justice in this country. The meaning behind the slogan never changed, but peoples understanding did.
