It’s not necessarily a good slogan if you live in a high crime area, where better or more policing might be highly desired. At least in the press, people calling for the defunding of the police were often co-located with some of the more violent riots of the last few years. I can appreciate that there are arguments to suggest that this is a false comparison. However, it must be admitted that the slogan was confusing and divisive, whereas not all issues around policing were nearly as divisive. (For example, there was broad support, and rightly so, for the jury verdict in the George Floyd case. )
