A quick note to our New York City-area readers: the ACLU's Catherine Crump, author Ken MacLeod, Cato's Julian Sanchez and others will be appearing at Cooper Union this Saturday for a panel on "Life in the Panopticon: Thoughts on Freedom in an Era of Pervasive Surveillance.” The panel is sponsored by the ACLU and Cooper Union as part of the PEN American Center’s Festival of International Literature.
