"Probably misprints and/or test sheets which is why they were left. Clearly, they didn't get those sheets from the US Mint. Why would they be copying/printing American $100 bills if not for some nefarious purpose?"
Agree completely. Even circumstantially, with heavy benefit of the doubt, why would you find such a thing in such a place?
Isn't even a question the press wants to bring up? Or the White House maybe? Just a casual aside from Tony Snow,
" . . . and we'd like to thank MSNBC publicly for the footage of the uncut sheets of what appear to be counterfeit $100 bills. We are requesting samples be collected for examination by US Secret Service to be detailed to the IDF as consultants to examine what was collected there at Qana . .."
The explanation from the MSNBC reporter was that these were xeroxed copies of real bills that the bank used to keep a record of and trace serial numbers. The copies were on standard paper and much smaller than real bills.
