I'm not going to pretend that I understand the finer points of the scam in this episode,as it is not something that should have been possible. Apparently it did happen enough times to make an episode about it,right? It seems a little far-fetched but I've fallen for dumber stuff.. It basically involves a small group that take advantage of loopholes in the way that money,promissory notes,bills of sale and so forth were processed and verified. The group manages to take advantage of time-lags in processing of property transfers,business contracts,and so forth. It is hard to believe that this stuff went on,I mean the lax security with the financial stuff-but it is still going on today,there will always be loopholes and people that take advantage of them.
