The guys with the overwhelming desire to protect and serve are the scariest I've met. They'll bend the rules quicker than anyone because they're convinced that they NEED to do something that's wrong for the greater good.
The cop who's just there for the perks says "no way man, if I break the rules they'll fire me and I can't get half price cheeseburgers anymore". The best cops I've ever met were there ONLY for the paycheck.
Why does that just make a strange kind of sense?
