Trust Game
This offense starts with the same scenario for the Handkerchief Switch. Once the suspects tell the victim they want him to hold the money for safekeeping while they have to leave for some reason, a discussion ensues about how to prove that each of them can be trusted with each other's money. All the collective money is placed in a handkerchief or bag and they take turns walking around the block and returning with it, to prove they can be trusted. When the turn comes for one or both of the suspects to walk around the block with the money, they take the package of money and do not return.
