I can't wait for this movie to come out. Before changing my major to radiology, I was studying criminal justice and once did a speech on this guy at UNO. If you haven't watched some of his interviews on youtube, I highly recommend it. Definetely a f'd up guy and obviously I don't condone what he did, but it is very interesting.
