I'm on my high horse here. They farmed it out to Think People because they were using the process to get to an end, to sack SM, and Think People would have played the game for them.
It's a small org with few resources so why not just try and treat SM fairly internally. The investigation implies she has done something significantly wrong which is nonsense and they knew it implied that which is why they signalled it to the world and his arsehole.
They should have just said to Sara would you mind keeping a lid on attacking specific groups when you are giving speeches about women's rights in future. And then allowed her outreach work to work with the many other communities than captured ones for a while.
Fuckers!
