Ok, saw your reaction with no reply, which means you won't.  Unless you have, you may miss out on the obvious that good behavior isn't legislated.  Good behavior and good government is a reflection of the citizens.  When the citizens give the government no reason to react harshly (such as armed cops), then the government can loosen its reigns and not arm its patrolmen.  

You're right...'civilized countries' don't arm their patrolmen with lethal weapons.  But it's because the citizens are civilized even without legislation or rule.
