are you sure that is all he did?
Nope but considering his name is Murphy and that he's the McCormick Professor of Jurisprudence, Emeritus, at Princeton University I don't think he's engaging in much terrorism.
I know Princeton and the name Murphy have been synonymous with the word terrorism in the past but I'd be willing to bet this guy won't be partaking in much terrorism in the next few years. Of course that's just a hunch.
Of course if you've got proof of something else I'd love to see it.
