So what should the police have done with no evidence, not even a witness sratement?
You definitely have the cart and the horse the wrong way round there.
There is no witness statement because the police officer wanted the woman to describe the penis, not the lewd act! She wasn't given the chance to report it, make a statement, get a crime reference number because the police officer made up their own law!!
It is not viewing the penis that is an illegal act. Or any woman who gets flashed at would be guilty of a crime.
It is flashing the penis that is the lewd act. The intent of the man when he chose to uncover and flash it at someone.
We used to tell young girls that when flashed they should look away and run, maybe even laugh. Now, according to this officer that would make any crime null and void!
Be fucking sensible!
Or do you think that any woman wanting to secure a conviction for a flasher should get up close and personal and have a good look, just to satisfy both pervert and police?
