These days you have to bear in mind that all bureaucrats' first and primary
purpose in life is justifying their existence so any excuse you give them to
light you up just proves how necessary they are. So you just made his life
easier and ours harder. ;-)
It's been going on forever. Look at this study at why assaults on NPS LEO Rangers exceeds the norm by almost a factor of ten:
The study's result? The NPS cooks the books. Non compliance, flight, general surlyness, drunken off duty mutual combatants and assault on civilians all are counted by the NPS as assault on their on-duty LEO's. They then come hat in hand to Congress for more money, to combat the non existent epidemic.
I believe that a lot of law enforcement is systemically untruthful about what the real perils facing them and us are. Their budgets are their primary concern.
