This is a legislative and judicial issue as well. Politicians, a fair number of whom are former judges, pass terrible legislation that is then prosecuted by DA's with little to no regard for justice (only conviction rates matter, right?), while cases are judged by former DA's who've managed to move up the chain a little. The management layer is a circle of incestuous self aggrandizing bullshit, and while cops are the boots stepping on the people, someone else to managing where, and how most of that stepping happens.
