This guy is OBL's kid. In the video in #140. He was actually at the scene in the Boston bombing.
Why is he so short when OBL was 6'5? Probably all the men on his mom's side were short and he took after them.
And we still haven't IDd the Uncle Fester right behind him, that person has no Arab blood but is approved to be among them, as a trainee, perhaps.
