Factual error: In the scene where Earl is fighting the other prisoner, he is using a "sword" made from a bar of metal, it has a blade that is well over 2 feet long from the tip to the hilt. At the end of the fight the other prisoner is standing with his back against a solid concrete pillar, but Blake somehow manages to shove the "sword" through him all the way up to the hilt. This wouldn't be possible unless Blake were somehow able to shove the bar into the concrete.
Factual error: I don't know what lousy hospital Denzel was treated at after being drugged and raped but no-one could have got his medical records without permission to know his test results. Furthermore his test results would have come back immediately, and he would have known he had an open STD in his system he would not have been sent home without it being treated.
Factual error: There is no way in any shape form or fashion will a TV news center air open pornography on TV being the scene where Denzel is being raped by the prostitute and shown all over the evening news.
