2009 Fort Hood shootings

Nidal Hasan, the Army psychiatrist who killed 13 people in the 2009 Fort Hood shootings, sends a letter to Abu Bakr al-Baghdadi asking to be made a ‘citizen soldier’ of the self-described caliphate:

I formally and humbly request to be made a citizen of the Islamic State … It would be an honor for any believer to be an obedient citizen soldier to a people and its leader who don’t compromise the religion of All-Mighty Allah to get along with the disbelievers.
