The Night of the Circus of Death

Paper currency issued by the U.S. government was generally considered unconstitutional before the time of Pres. Grant. The U.S. Constitution only allows Congress to "coin" money and only allows legal tender coin to be used for legal payment. Before then, only paper currency issued by private banks (hence the term banknote) were circulated. Once the Civil War broke out, the U.S. government resorted to printing paper currency (the original greenback) in order to help pay the enormous cost of prosecuting the war. The presumed unconstitutionality of the greenback was temporarily ignored until the war was over. Once Grant was President, he nominated two judges to the Supreme Court whom he knew would rule in favor of the constitutionality of paper money, much as abortion is the litmus test for the nomination of a judge now. It was the issuance of paper currency by the US government, and the problem of counterfeiting, that led to the creation of the Secret Service, an agency of the Treasury Department.

Near the end as West and Gordon are following Lennox, West tells Gordon to cover the back. Gordon nods and walks off (not speaking). As he walks off, it's briefly evident that the actor is not Ross Martin.
