The police don't exist to protect citizens from crime. They exist to squash "illegitimate violence", not because it benefits you or reduces crime, but because the police exist to enforce the state's "monopoly on violence". Their role is to do violence to you, not to protect you from it. The money that is levied from you is used to pay for the interests of the state, not your interests. They don't work for us, no matter what you might hear from 1AAs.
