Ok, I love how this page seems to have been swarmed with DOWN WITH THE US IMPERIALISTS, and AMERICA == TYRANNY style comments.
The parent article is incredibly slanted - the author ever so conveniently forgets to mention that his son was a senior Al-Qaeda recruiter, who was "advisor" to the 9/11 bombers, the Fort Hood shooter, the underwear bomber and a whole host of others.
Even his own Yemeni government tried him in absentia, and ordered him captured "Dead or Alive".
You can argue that the death penalty is wrong, and he should have faced a US court (although I somehow down he or say Osama Bin Laden was likely to actually show up in a US court, even if given half the chance).
However, please don't be another ignorant reader who doesn't know where Yemen is, or any of the context here.
