Here is an example of the horrendous torture.
A gun was fired in an adjacent cell leading the terorrist thug to fear that someone was just killed and that he was going to be next.
That's way worse than having your neck cut off with a rusty cutlass.

Most people end up with worse treatment in the form of pranks by older siblings than Gitmo inmates have suffered.
