I've said before that this guy is actually a bit of a government tool. I also mentioned that he is, without a doubt, entirely against torture. Dr Schulz encourages foreign governments to investigate US officials, and to arrest those found guilty if they enter their countries for what has happened at Abu Ghraib and other detention centers.
Dr Schulz, again, is only complaining about torture. Dr. Schulz names Donald Rumsfeld, and numerous other lower people.
Click on the Amnesty International's 2005 Annual Report on Human Rights to watch Dr. Schulz's remarks on Abu Ghraib. The text of the report is available at the Amnesty site.
