I saw a college teacher on twitter observing with some distress that the students hadn't even heard of Abu Ghraib. And, yes, I wouldn't mind The Kids Today being aware of such things, but in about 5 years, college sophomores are barely going to be aware of 9/11.
I was a college sophmore in 1991 and I don't think I knew all that much about anything that happened in 1974...
2004 was a long time ago, already, is my point.
