Plot hole: Where do the flyers come from that are in the bags that are carried out of the vault and into the van? Danny and Linus couldn't have taken them down there and there is no room with the Chinese man, and they are carried out to the van before the SWAT team appears, so they had to be in the vault to start with? [On the DVD version the audio commentary with Steven Soderbergh, he states that getting the bags of flyers into the vault is an error and that even he doesn't know how they would have gotten down there.]
