Judge Advocate John Bingham presented the closing argument for the prosecution. The military tribunal had jurisdiction, he said, not only because the court itself had ruled at the beginning of the trials that it did but because they were crimes committed in a military zone, during a time of war, and against high government officials in carrying out treasonous activities. Bingham pointed out that the Surratt boarding house was where the conspiracy was planned, and Atzerodt, Booth, and Powell had all met with Surratt. Booth had paid for the rental of the carriage that took Surratt to Surrattsville each time, and Bingham said that was evidence that Surratt's trips were critical to the conspiracy. Bingham also said that Lloyd's testimony had been corroborated by others and that his unwillingness to reveal the cache of weapons in the tavern was prompted by his subservient tenant relationship to Surratt. Bingham concluded by reiterating the government's key point: Powell had returned to the Surratt house seeking Surratt, and that alone was proof of her guilt. Bingham also pointed out for the tribunal that the charge a person was indicted for was irrelevant. Under the law of conspiracy, if one person carries out a crime, all conspirators are guilty of the same crime.
