Well, we've spoiled our police force. We've provided them with ridiculous amounts of power, minimal oversight, and very rare and minor consequences.
The behavior you describe is that of a spoiled child, used to getting what it wants immediately by throwing an abusive tantrum, consequences to others and rules be damned. Same reason they execute PIT maneuvers on busy roads, lead high speed chases through the middle of towns, and empty full magazines into densely populated areas, all things that police in other countries are trained not to do, trained to be patient and follow instead. They want it now, and anyone hurt along the way is just a casualty of war, not their problem or responsibility.
