I haven't see a thread about this, but am really posting as I heard Lady Angiolini being interviewed after her report came out about Wayne Couzens. The interviewer, perhaps obviously asked why the police had let someone known as the rapist to continue to be in the police.
She said they had not found anyone who had said or had every heard him called that, but that everyone knew about his consistent indecent exposure. Which she felt, as others have also said, is a common indicator of a man who is likely to commit an act of sexual violence against a woman.
Lady Angiolini makes many important recommendations about police vetting, but about two thirds of her report focuses on a long-ignored issue: that masturbatory indecent exposure is both a serious offence in itself and often a gateway to even graver crimes. Four months after scaring that cyclist, Wayne Couzens abducted and murdered Sarah Everard.

Do the police / CPS even bother to pursue men who expose themselves or is just seen as a minor crime.
I thought it had now become well known that is was a sign of a potentially dangerous man.
Or is it just another of those issues that are ignored because only women are impacted by it? Or one of those boys will be boys responses?
