We're each entitled to our own perspective, but fwiw, I think you'll struggle to find any cohort less accountable than the police. Whereas "the mob", being traditionally a phrase used broadly by established powers to derogate the opposition, is almost by definition always the cohort held most to account in any given situation.

Furthermore, perhaps one of the biggest false assumptions many seem to have about abolition movements is that there isn't reasoned proposals for (existing or new) accountable institutions to fill potential voids left by abolition.
