It could be.
Become a CSM, swipe the money collection cart. Then using the keys provided in accounting (where you would originally leave the money)... take the tapes out of the security room.
Just have an alaby ready, a tape of an area you weren't in put in the overnight manager's car underneath the driver's seat with a few random fragments of tapes. When crushing the tapes keep the film, wear gloves, and a disposable poncho. Put all that in a bag, which is then put into a ziplock, get rid of that bag somehow, then go home and shower. Obviously don't buy the bag/poncho at walmart or anywhere near or recent. Have a friend pay cash for it.
Or you could just say that you'll detonate a bomb in the store if x amount isn't transfered to your overseas account. I heard walmart ran into that problem and gave some dude $26,000. Dunno if the FBI caught him
