The Accra Psychiatric Hospital occupies a sprawling block in the heart of Ghana’s capital. Walls the color of aged parchment rim the compound, with coils of concertina wire balanced on top, making the hospital within appear more labor camp than home for the sick. Anas Aremeyaw Anas spent seven months last year casing it, posing first as a taxi driver and then as a baker. On the morning of November 20, 2009, Anas adopted yet another disguise, matting his hair into dreadlocks and pulling on a black button-up top. Three of his shirt buttons, along with his watch, contained hidden cameras.
