I read on another thread, and I hope the poster was mistaken, that once a rapist utters the magic words the prison service treats them as a woman. This includes risk assessments and offender treatment pathways, designed to cut reoffending, which aren't as effective on tw because they are men.
A chief of police stated that tw officers can carry out intimate searches of women. I expect this also applied to prison officers who are trans. Women prisoners who object to tw or, God forbid, misgender them can be punished. It can even affect their chances of parole.
There was recently a tw, jailed for paedophilia, who was put in a women's jail that has a mother and baby unit. He didn't even have a GRC. I believe he was eventually moved to a men's prison after he struck up a relationship with a woman who was described as young and extremely vulnerable.
