I've never really understood why this works. I'm a little embarrassed that it does in the home of the brave and the land of the free. There would be an extraordinary series of unfortunate accidents if this sort of thing was done to the wrong element in society. Fires, explosions, shootings... When you think about it, nobody guards the homes of district attorneys, police or judges.
I don't think a passive society was what they had in mind when the founders launched the Revolution. What total morons decided that incentivising the police and all other law enforcement agents to stop and steal was the best route to a just and civil society wherein all people had respect for the law? This is no different than a highwayman standing in the road and shouting, "Your money or your life!"
