evidence against bin laden?

[brad]

ok im not the brightest kid on the short bus.

but what exactly is the evidence against bin laden?

i know at least one (and probably both/all) of the bin laden videos were proven to be fakes, so is there anything else besides that or is that it?

i know way back the taliban in afganistan said they wouldnt turn him over without some evidence and the US said turn over or else and invaded without citing any.
