Before he was patrolling the dusty roads of Afghanistan, Captain Kirk Black was a police officer and SWAT team member in Baltimore. Although quite skeptical when it comes to hearing prisoners’ claims of innocence, Black found the case of one Afghani detainee, Gul Khan, perplexing, and decided to investigate pleas from Khan’s relatives that the U.S. military had mistaken him for another man suspected of being in the Taliban. Black eventually concluded that there was a “mass of evidence” indicating Khan should not be held prisoner at Bagram Air Base, where about 600 other detainees have been held captive without charges or trial. The Army captain eventually contacted a human rights lawyer about Khan’s case, which may get a hearing in federal court depending on the success of a habeas corpus petition that’s been filed by attorney Clive Stafford Smith.
