Character mistake: The complaint that Robert Duvall is reading has a very obvious typographical error describing the decedents' conscious pain and suffering, 'concously'.
Character mistake: Sheridan (as Roberts) takes a job as a tow truck driver while laying low from the U.N. killings. He claims he had the gun for protection, but he must have realised if he ever had to use that weapon on the job his prints would have been run anyway, so why on earth would he take any kind of job that requires him to need a weapon if he's trying to lay low?
