Yes, that which your friend emailed you really happened...and much worse. Here's more (don't worry DU admin, there are no graphic pictures here, just text which offers proof positive of the torture and rape of Iraqi women and children at the hands of US soldiers and US-hired interrogation contractors:

Some of the worse that happened that you don't know about, ok. Videos, there are women there. Some of you may have read they were passing letters, communications out to their men. This is at Abu Ghraib which is 30 miles from Baghdad <...>
The women were passing messages saying "Please come and kill me, because of what's happened". Basically what happened is that those women who were arrested with young boys/children in cases that have been recorded. The boys were sodomized with the cameras rolling. The worst about all of them is the soundtrack of the boys shrieking that your government has. They are in total terror it's going to come out.

Other pictures, which the world has not seen, but which are in the hands of the US military, include shots of a dog attacking a prisoner. An accused soldier says dogs are “used for intimidation factors”.
There are also pictures of an apparent male rape. An Iraqi PoW claims that a civilian translator, hired to work in the prison, raped a male juvenile prisoner. He said: “They covered all the doors with sheets. I heard the screaming ... and the female soldier was taking pictures.”
