Eh? Domestic terrorism, maybe. Al Qaeda, I'd have to doubt.
I don't think he's gonna end up being Mid-Eastern either. And I also think he'll be caught this week. He's basically throwing himself out there now, what with the jumping out of his van to take the shot at that unfortunate FBI worker.
Hopefully, he won't have to stand trial, and will be "shot attempting to escape" rather than arrested.
From the Al Qa'eda Training Manual:
Missions Required of the Military Organization:
***********
3. Assassinating enemy personnel as well as foreign tourists. [Emphasis added.]
I wouldn't so quickly rule it out.
