My political leanings are skeptical; it seems to me that the objectives of the police and prosectors are (respectively) to preserve the police and the prosecutors. When crime increases, the police say they are underfunded and overworked, while prosecutors call for additional funding and powers. When crime goes down, they claim it is thanks to their intelligence and dilligence. Both groups are also known for avoiding being held responsible when they fail at their jobs (such as by shooting unarmed people who happen to also be naked, or convicting the innocent through fraudulent evidence).[1][2] Are the police and prosecutors really focused and achieving the maintenance of an ordered society, or are they just keeping their jobs?
