Two days ago on NPR I heard a story about Abu Ghraib, where the news reader referred to "the alleged abuses". Not "torture" - "abuse". Now, I don't think there is any question that there was abuse. One needs only to look at a few of the photos. And I don't think that anyone is claiming the photos are doctored, or otherwise untrustworthy.
So here we have something that is about as close as we can get to a consensus fact: that there was "abuse" in Abu Ghraib. The media have gotten completely silly about the use of "alleged". The word means that something has been asserted by somebody, but that something is questioned by at least one other person.
Was there "abuse" in Iraq? Yes! It's as plain as the alleged nose on my face.
