They're not comic book villains, you know. They're human beings. I'm pretty sure a standard maximum security prison could handle them.
Typical idiot pinko. Contrary to what the liberal media tells you, suspected terrorists (all of them) do actually have magical powers. A member of Al Qaeda merely has to look at a door and it will open. Senior members can actually melt walls that haven't been specially treated. To say nothing of their powers of flight, mastery of disguise and astounding linguistic skills.
Actually, I think it's more likely that they'd macgyver some bombs behind bars and then suicide bomb their way out of prison.
