I think Cathy was the former police officer who exposed the strip search guidelines that said that men could search women if they identified as female.

"Mrs Larkman, 54, grew increasingly concerned with the declining trust women had in the police following a spate of scandals including the abduction and murder of Sarah Everard by a serving police officer.
Last October, responding to fears among some women that they had no option over the sex of the officer searching them, she wrote letters to the College of Policing, the Police Federation and the NPCC seeking clarification that this was not the case.
The mother-of-three, who is being supported by the Women's Rights Network campaign group, knew that under existing law strip-searches had to be carried out by an officer of the same sex.
But she was left 'absolutely gobsmacked' when the NPCC finally released its new guidance to her last week.
'The more I read it, the more shocked I was,' she told The Mail on Sunday. 'This is a devastating blow to women's trust in the police. Women are not even an afterthought in this guidance — they are completely non-existent. Everything is geared towards the sensitivities of the officer doing the searching.
'They claim they are trying to be inclusive. But this isn't inclusive of women and it doesn't respect their sex.'
