T he police came for me on a cold, rainy Tuesday night last month. They stood in front of my home in Islamabad, four men with hoods pulled over their heads in the driving rain. The senior officer, a tall, clean-shaven man, and I recognized one another from recent protests and demonstrations. Awkwardly, almost apologetically, he handed me a notice ordering my immediate expulsion from Pakistan. Rain spilled off a nearby awning and fell loudly into puddles.
