Cops love to make people look and act stupid; like the time, I stopped a guy for a reason (whatever),,,I walked to the door and ask for his driver license, registration,,,yada yada yada...he looks at me, with a serious face, and says, "You can't stop me!" I look at him with same expression and say, 'Oh, I'm sorry...!" I give him his belongings, get back on my motorcycle and drive off!
He later called the station and demanded to know why I didn't write him a ticket!
In your case today, what would've been funny was for the officer to return to his car and drive off! that's my sense of humor...
I've got thousands,,,,plus tens of hundreds of the gruesome ones...and before anyone asks, no I didn''t carry bullets in my gun.
