". . .how far down it has gone?"

Hitch says that, regarding Abu Ghraid, the worst is yet to come:

The graphic videos and photographs that have so far been shown only to Congress are, I have been persuaded by someone who has seen them, not likely to remain secret for very long. And, if you wonder why formerly gung-ho rightist congressmen like James Inhofe (“I’m outraged more by the outrage”) have gone so quiet, it is because they have seen the stuff and you have not. There will probably be a slight difficulty about showing these scenes in prime time, but they will emerge, never fear. We may have to start using blunt words like murder and rape to describe what we see. And one linguistic reform is in any case already much overdue. The silly word “abuse” will have to be dropped.
