Taking this on face value.
I believe that Labour believe that they could have this policy.
I don't believe they have actually thought it through.
I don't believe that there are enough judges or court space to hold the trials.
I don't believe that the police can be trusted to obtain, keep and hand over any viable evidence that could help to bring justice to women.
I don't believe that the rape cases would end up with more men being found guilty.
I don't believe that if they were, that the men could be found places in prisons.
I don't believe that the Labour Party would keep men who say they are women out of female jails.
I would absolutely love to believe that any of this is possible, no matter who was the party coming up with it. It seems like it could be a way of trying to win back women to vote Labour. Which means that they think they might lose. So that's interesting.
