What gets me about this case is the way that his father has been acting. He talks as if MIT committed a great sin by alerting law enforcement to his son's crimes.
He was recently the subject of an article in the Chicago Sun-Times as saying that MIT needed to apologize for its actions and to do what his son wanted them to do: make journal articles and academic journals free of charge. Given the fact that academic journals are pretty expensive to publish, if they were made free, pretty soon there would be no more academic journals around.
