Other mistake: When everyone in the audience and everybody at the betting board see the original unedited version of what really happened at Bakersfield, it shows a soldier hitting Ben with the butt of his weapon from Ben's point of view, which is an impossible camera angle. And as it's the original unedited footage, it won't be something they faked.
Other mistake: Just before Arnold arrives at his brother Edward's apartment, he walks across a plaza. Note the people standing/sitting in the background, along the railing. They are still there, apparently not having moved an inch, in another scene of that plaza which is supposed to be much later after Arnold has been caught, sent to the tele-station and gassed unconscious.

Other mistake: The list of possible prisoners contestants the computer goes through shows different information, but the page with the 8 rows of double letters and numbers remains relatively the same, even though it's suppose to show variations and different information (i.e. AA always has -583 and -5483 and BB always has -484 and -4838).Bishop73
