There are so many comments worth responding to in this thread, but this one in particular raises my ire. Are you really trying to reduce policing tradition in America to western films? How about the real west, where self defense was a way of life. I don't want to be too combative but I seriously don't understand peoples inability to understand the principles of self defense as a natural human right, and yes that includes killing when applicable. It just reeks of a naive liberal mindset when people try to say you shouldn't shoot someone who breaks into your house in the middle of the night. Police don't have a duty to protect you, and very often will not protect you, and most of the time will just draw chalk lines around the bodies.
Its your own responsibility to protect yourself and your loved ones or other people who can't protect themselves, that's a fact, and it's high time the anti-gun crowd pulled their heads out of their ass, because a gun equalizes an otherwise unequal situation.
God made humans, Sam colt made them equal. I'm an atheist but the principle still stand. This goes for one of the most vulnerable classes of humans as well, women.
As a combat vet I have some major issues with the militarization of police, and their poor training/methods, so I got a bit ot. If we were to have a real conversation, I think we would be better served to talk of the pinkertonian origins of policing, or the CIA/FBI influence on it (eg. OccupyWall Street snipers), and the general lack of punishment of oath breakers, or the thin blue line.
Instead far too many use it to pivot to a session of anti-gun circlejerking.
