Where's Bin Ladin?

[civilian]

Saw report that Bin Ladin's youngest son may have been killed recently by a hellfire missile in Pak on a couple different news outlet. I found it interesting that the intel official mentioned that it may have been possible that the son may been held in Iran under house arrest. My theory/vote/opinion, whatever several months ago and a few pages back, was that Bin Ladin could be in a compound under similar circumstances Iran. I understand the prevailing wisdom is that no one has seen him for a very long time. I couldn't name one reason why it would benefit them to withhold showing Bin Ladin in a video. Could Iran be giving him medical care and preventing him from leaving or making videos? I'm amazed it has gone on this long. I know I'm not offering anything new here and has been discussed, but thought I would keep the question current on this thread since there is a poll here on his supposed condition or whereabouts.
