By Mohamedou Ould Slahi for ACLU - If I wanted to, I could put my pen down right now, close my office door behind me, and go for a long walk outside. Today in Nouakchott, Mauritania, it is terribly hot and dry, so that would not be the wisest choice, but freedom is having that option. And freedom is choosing to write instead, not because my life depends on it, but because these days, thank God, it finally doesn’t. A year ago this week, a U.S. military cargo plane touched down on this city’s arid runway and I was escorted, unshackled, down the airplane’s ramp and toward a group of government officials. With each step I pulled farther ahead of my American guards, farther away from the territory of bondage, and toward the territory of freedom. Hours later, a car turned onto the street of the house where I grew up and I was swarmed by family members and supporters. And then I was standing inside the house, just a few feet away from where I sat one day when I was 11, listening to the radio as they announced names of children from around the country who had made it into high school. Getting into high school was a big deal back then: There were few slots, and many who passed all their classes still did not make the cut. Those who managed had their names printed in the military dictatorship’s official newspaper and read over the air for the whole country to hear.
