Not sure what to make of this mess. What I would like to know is who had jurisdiction? In 1922, neither the FBI nor its predecessor, the Bureau of Investigation, existed. Hoover joined the DOJ in 1924 and I believe the FBI was established in 1930, or thereabouts. Now, the Mint itself was not robbed. But seeing as how money was not insured until FDR signed the Banking Act of 1933, which authorized the FDIC, it would appear this was a matter for local law enforcement to solve. The money taken was never recovered; although the principals were identified, none were taken into custody. The use, by the Director, of the term "machine" to refer to the getaway Buick touring car, is quaint. The haul was distinctive: 40,000 five-dollar bills. Afterthought: I do not believe even assassinations of Federal officials, like the president, were Federally prosecuted until legislation was passed in 1964. If I am mistaken, feel free, anyone, to take me to task. Great job, Roger!
