Last week, LIRNEasia taught a course on broadband policy and regulation in Sohna. One of the modules was on privacy and surveillance. One of the instructors was Sunil Abraham, acknowledged for his thoughtful and creative approach to sticky ICT policy questions. Drawing a diagram, he pointed out that if surveillance was exclusively focused on the small percentage, perhaps five percent, of people who were engaged in terrorism or other bad acts, law enforcement would be more efficient and the liberties enjoyed by the non-terroristically inclined majority would be that much safer. On the face, a beguiling proposition.
