You must not realize how easily all of the fraud can be tracked down. You start with the brokerage firms which processed the paper. We already know that RME had a big account with TD Ameritrade. All of those records can be subpoenaed. There are other firms through which many shares of Spongtech were processed as well last year. I know who many of them are and where to start looking for the paper.
Then you go to the transfer agents. That's a piece of cake. There were two of them. The records can be subpoenaed.
Plus you have the promoter trail. All of those people and all of their communications will likely be subpoenaed.
When it is all over, you hand the package over to the DOJ and let them do their thing.
