"...After reading the file it became obvious that Tovey was satisfied with Leach and Wake Walker's performance..."
...was satisfied with Leach and W-W when he (Tovey) made it clear that any action taken against these two men would be met with Tovey hauling down his flag and acting as Prisoner's friend. All talk of action evaporated at that point...
This is rather old news; I'm surprised you're claiming no such action was considered yet--somehow--Tovey quashed all talk of such action. I guess he dreamt it all up.
