The data may have been open source...but the mechanism to extract it from those sources may be quite unique and state of the art...way beyond Google. The collection mechanism and algorithm was IMHO part of the programs uniqueness.
Remember that this program, which ran on a secure computer system and a hackproof network, generated terabytes of background data.

However, if you have the background data generated by the program...and the program source code...you could in theory recompile the program and regenerate any and all reports from the archived data. The report process should also be part of the program.

To prove that this team fingered Atta in 2000, you would need to get the archived background data they had back in 2000, and regenerate the reports as they originally did in 2000.

Now it would be very interesting if both the program source code and the archived data from 2000 were BOTH erased, wouldnt it?

Indeed. But they've had three years to 'rebuild' what was taken away when AD was put to pasture. I'm just saying that the original distillation of Atta & plan has probably been created again, using all the tools they originally used. It's a good thing.
