Warning - grim pictures from Abu Gharib

What seems strange is that the techniques don't appear to have any modern sophistication to them. Just pain and fear. You would have thought they would have some greater skill or direction to them, rather than just random beatings, humiliation and terrorising.

I seem to recall there are a few posters on here who have little problem with these practices as the people who are tortured and killed are always guilty. In the light of this how do you think the US army could modernise it's techniques and improve results (whatever results were intended - it seems a little difficult to fathom here).
