You can read a summary of, listen to, or watch streaming video of Hersh's speech via Eschaton.
What I also find interesting is how this story fell down the memory hole for a few months. Remember this piece of news from May?:
U.S. military officials told NBC News that the unreleased images [of abuse at Abu Ghraib] showed U.S. soldiers severely beating an Iraqi prisoner nearly to death, having sex with a female Iraqi female prisoner and “acting inappropriately with a dead body.” The officials said there was also a videotape, apparently shot by U.S. personnel, showing Iraqi guards raping young boys.No? Doesn't look too familiar? Perhaps that's because it got edited out of NBC's report soon after it was first published.
