This is fair and good, but not the whole story. Recruitment has emphasized the macho and gun aspects of policing in many jurisdictions, abetted by the provision of military equipment to PDs (including grenades and rocket launchers to LA school district FFS). There is a significant socialisation and culture problem within many PDs, due to lack of effective feedback mechanisms against such abuses of power. Add that to the inevitable draw of PDs to psychopaths (*notallcops ;) and the problems get out of hand, as we have now.
