I know I meant to start one ages ago, to highlight wrongdoing by people in the justice system.
Well, I'm going to start one now, with this story, although it is about prison officers rather than police.
A prison officer sexually assaulted a female prisoner, and started what the BBC laughably call "a relationship" with her that lasted 3 years, during which he also involved another prison officer who also had sex with her.
:(
Feel free to add any other stories you see about police/CPS/prison officer crimes against the women under their control.
