"All intelligence services rely on convincing the public that there is a monster out there in the big wild world waiting to grab them." The truth is more complicated, as KGB founder Felix Dzerzhinsky could tell us
US military think-tank studies 17 documents captured in raid on Al Qaeda leader's compound last year. Main theme: Bin Laden's frustration with his inability to exercise effective control over regional jihadi groups (PDF)

On the life and "career" of David Headley, spy, militant. Pakistani-American, born Daood Giliani. Revealed Pakistani intelligence role in Mumbai attacks. Slid among different cultures with ease. Life a mass of contradictions
