BTW: $25 says the officer never touched her...
I think that you are right.
Sooo ... why was a cop concerned with two kids getting it on in a car, in the first place?
Dumb use of resources.
There is no excuse for an officer slapping the nude buttocks of a woman caught performing a sexual act in public, not with OC spray and/or a PR-24 hanging on the belt.
I’m skeptical too, and as amusing as this story is at first blush, his livelihood is on the line. I’d guess that this girl was so embarrassed she cried foul to save face.
