Investigative reporter Jane Mayer of The New Yorker magazine revealed last week that the number of US drone strikes in Pakistan has risen dramatically under President Obama. During his first nine-and-a-half months in office, Obama authorized at least forty-one CIA missile strikes in Pakistan—a rate of approximately one bombing a week. We speak to one of the most high-profile critics of the US drone program: Philip Alston, the UN special rapporteur on extrajudicial, summary or arbitrary executions. Alston says the US government’s use of Predator drones may violate international law.
