Reminiscent of North Korea where people were terrified not to cry enough or look distraught enough at the national funeral, because they knew they were being watched for their reaction and would be punished if it was wrong.
There is no thinking this through or looking ahead. If every self ID'd TW in the prison system goes into the women's estate there are several obvious things that a child could forecast.
The rate of identification among male prisoners will explode. This will be for many reasons. Talk to prison staff, they'll give you a list off the top of their heads, and it'll include 'sheer boredom', particularly from serious crime prisoners with years ahead of them, wanting any kind of control or change in the monotony. Not to mention that sex offenders like controlling women, it's a hobby of theirs, with very little scope to enjoy it in the male estate. The huge numbers of male born, biologically male prisoners needs to be considered for several reasons. The high proportion of the self identification in prison coming from the sex offenders list is also relevant. Bearing in mind that less than 2% of rapes end in a conviction, someone doing a sentence of several years for serious sexual offending has had to do something extreme and probably repeatedly.
With the numbers involved, the fact that women make up only 5% of the prison population, and that there are 8 dedicated category A male prisons but only 2 female prisons that take category A female prisoners as well as other categories, the tipping point is quickly going to come where the higher security women's prisons become either equally mixed sex or actually male dominated. It may be manageable to have one single higher category male prisoner managed in a lower category, lower security female estate: when it's approaching equally mixed sex with half higher security than the other half, there are going to be fundamental practical issues on how this is managed.
If additional women category A provision has to be created, it will be almost entirely male prisoners. The prison service (currently) won't put a TM in a male prison, because even they baulk at the risk. By how many do women have to be outnumbered by TW before that risk becomes much the same?
And how many women harassed, intimidated, assaulted, raped or worse is 'acceptable collateral damage'? Give us a number, Nandy. How many vulnerable women are you willing to feed to your political ideals?
