Investigations take time. This one apparently WAS known of before one of the defendants' lawyer decided to go outside the system.
My question is not how long did the investigation and publication take but how soon was the on-scend situation corrected, how long ago was that, and what conditions are today.
Seems to me that should be the focus and not the bureaucratic and political shenanigans that followed.
Next, we should be asking how classes of prisoners were segregated in the facility and how their treatment differed. Who knew what and when should be addressed well after questions such as these have been answered.
PS: Anyone thinking that prisoners with potentially critical information are best dealt with by fattening them up, making nice, then asking politely where the nerve gas is buried - is X*&%$#!! nuts!
