by design, the police concentrate force in a separate group of people who then specialize in that use of force. residents relinquish that (threat of) force voluntarily to the police to enjoy being a citizen of a (hopefully) more peaceful society in exchange.

part of the problem is that we naturally conflate (1) knowing and enforcing rules and (2) the use of force. despite the similarity of the words, enforcement doesn't necessarily require direct force. such intertwined subtleties make your entreaty to "institute checks and balances" hard to realize.

and this disjunction is problematic; i think it's better to have a little force spread widely throughout communities, rather than a lot of force concentrated in one sub-group, as its less risk of catastrophic use of force and a more even application all around (more fair). but that's a challenge in the increasingly specialized social groupings (and identities) we live in.

even so, "police" is too much of an identity separate from the society to which they're enjoined. i think policemen/women should be community members first, and enforcers second, not the other way around.
