Karim Khan is a lucky man. When you’re picked up by 20 armed thugs, some in police uniform – aka the Pakistani Inter-Services Intelligence (ISI) – you can be “disappeared” forever. A mass grave in Balochistan, in the south-west of the country, has just been found, filled with the “missing” from previous arrests. But eight days after he was lifted and – by his own testimony, that of his lawyer Shasad Akbar and the marks still visible on his body – tortured, Mr Khan is back at his Pakistani home. His crime: complaining about US drone attacks – American missiles fired by pilotless aircraft – on civilians inside Pakistan in President Obama’s Strangelove-style operation against al-Qa’ida.
