An update on the attack at Frankfurt airport, March 2010:
A Kosovo man has told a German court he shot dead two American servicemen at Frankfurt airport but said he did not understand why he had acted as he did....

"What I did was wrong, but I cannot undo what I did," Uka told the court in Frankfurt at the opening of his trial. Uka said he carried out the attack after watching a video purporting to show US servicemen raping a Muslim girl in Iraq.

In fact, the video was a scene from Brian De Palma's anti-war film, Redacted.

"I thought what I saw in that video, these people would do in Afghanistan," Uka said.

A strange case of a 'Lone Wolf' attacker, although maybe not so unexpected given all the propaganda in the public domain.
