"The modern police-driven model of law enforcement helps sustain a playing field that is fundamentally uneven for different players upon it. Modern police act as an army of assistants for state prosecutors and gather evidence solely with an eye toward the state's interests. Police seal off crime scenes from the purview of defense investigators, act as witnesses of convenience for the state in courts of law, and instigate a substantial amount of criminal activity under the guise of crime fighting. Additionally, police enforce social class norms and act as tools of empowerment for favored interest groups to the disadvantage of others. Police are also a political force that constantly lobbies for increased state power and decreased constitutional liberty for American citizens." An excellent essay by Brad Spangler.
