I don't think sharing information you haven't asked for permission to share should be acceptable. So I have no objection to it being an offence tbh.
I accept your point. I think I'm just seeing it as part of a larger picture.
But not for the purposes of reporting crime (unless it is essentially part of the investigation, I suppose - eg 'be on the lookout for this person who may be presenting as ...')
I think this is where people are getting confused. The transwoman rapist who absconded last week had only recently transitioned. She took off her wig and make up and dressed in her male clothes after the crime. It was reported that the police were looking for a woman who may be dressed as a man.
Which to me, is a completely unnecessary and misleading head fuck. And if her identity were to be enshrined in law, it would be completely legitimate for them to report in that way.
