The conversation in the prison yard between Ross and Fargo Red, concerning dogs not having pores, is unrealistic. The slow-witted Red would surely have heard the word as "paws". As such he would not then have asked "How do they sweat?"
After the final prison riot is over. The next shot is of a newspaper headline which reads: Gov. Hanley charged with murder; Grayce is named as accessory!', with the sub headline: 'Warden of Rocky Point corroborated by dying deputy; accuses pair of Ross frame-up'. The only other guard other than the Warden that was in the solitary block at the time of the confession who could have corroborated anything was Lang who was in the cell with the Warden. Lang was not even injured during the riot, so would not have been dying.
