You guys talking about the police beeing "over militarized" its not a new thing. Sir Robert Peel built the foundations and organized the London Metropolitian Police Department. His pattern for that Department is the what all other departments since have been bassed on. He had a group of guidlines known as "Peels Principles" one of those is the police be Organized along military guides such as Rank structure and training. Now this was said and done back around 1829 so military guidelines were diffrent then but this is the basis. Peel is known as the father of modern policing.
