In November 1881, Charles Guiteau, a charlatan suffering from mental illness, stood trial for the assassination of President James Garfield. As part of his erratic defense, Guiteau argued that he should not be charged with murder, because the bullets he fired from his ivory-handled revolver didn't kill the president. Instead, Garfield died as a result of the care he received from his doctors. "I deny the killing, if your honor please," he said. "We admit the shooting."
