the specific people who are most hurt by bad law enforcement also tend to have the least power to "get some new servants."

so who's fault is that? usually not the victim. or at least the most direct victim, since obviously, society as a whole is hurt by this sort of thing (just not as much as the person who's wrongly harassed/injured/killed by the cops).

but maybe your point stands, because is that really a "legitimate democracy"?
