The less cops, prison guards, & soldiers we have, the better. The more money spent on cops, prison guards, & armed forces, the less money we have for schools, health care, etc. It's a zero-sum game. Moreover, the more individuals have law enforcement jobs, the more likely the war on crime is to continue, since organized cops, etc. lobby for tougher laws on crime & less civil liberties. The general interest of the working class and the particular interest of the armed agents of the state are inherently contradictory.
