all you want to knwo is how they have Osama's DNA, right?
I'm not sure, it would be speculation like anything else, but all I know, is they don't really need it. bin Laden DNA would be enough with corroborating evidence, plus his body.
Honestly, though, where would they be able to get confirmed DNA from Osama previously? not terribly likely. You have bin Laden DNA, a body, solid intel, shit tons of family members to ID the corpse.
why are you prattling on about this?
I do work with DNA on a daily basis, though. I can tell you, all they need is family DNA.
