On November 14, 1881,
Charles Guiteau went on trial for the assassination of
President James A. Garfield.

The trial of Guiteau, a probable paranoid, pointed up problems with nineteenth century
law's treatment of insanity; Guiteau's trial is also problematic in retrospect as Garfield's death was immediately attributable not to Guiteau, but to Garfield's doctors who - before sterilization was well understood - repeated probed his wound with
unwashed hands while searching for an embedded bullet.
