They enforce rules. They enforce regulated societal norms. They take it out of the "kill or be killed/only the fittest survive" mode. For those against regulation, let's get rid of the cops, too. Then we'll see who is really top dog.

Capitalists love deregulation of financial systems, but are the first to call the cops when someone tries to steal their money. Banks screw people with fees, exploit the poor and double-charge on bounced checks, but the Feds will put bank robbers in jail for 7 years for an average of $3500 robbery.

Double standard.
