Accidental anarchist: Read the book "Rise of the Warrior cop" it came out in 2013, it explains in detail on how we have gotten to this point. You also have to remember that a lot of the cops now on the streets have military combat experiance, policing and combat experiance are not compatible, the mind set is 180 degrees apart. It becomes an us and them mindset, and "them" is anyone who does not respond to a cop with enough deference or humility. They can have attitude but you better not have it in the least. There are many cops who believe they ARE THE LAW not that they are to uphold the law and those laws also apply to them.
