Character mistake: Two police officers went to the Davenport's house because someone "requested a drive-by in the middle of the night." The veteran cop rang the doorbell, knocked on the door, heard noise (dismissed as "probably a pet"), and even yelled, "Rise and shine, people." He told the rookie cop that he was "trying to go the extra mile to make sure these folks are okay" and "Somebody called in a drive-by and I want to see their smiling faces." The officers nonetheless left when they got another call. (00:19:19 - 00:20:41)
Character mistake: Chris explains about the APV being behind the door and specifically states it has 16 wheels. When we see the APV it has 4 wheels on each side. Meaning 8 in total. For it to have 16 wheels as stated, all the wheels will have to be doubled up. However its clear that at least 2 separate wheels are single. Since Chris is right with everything else he has said in regards to the prison, there's no reason he would be wrong about this one thing. (00:56:00)
Character mistake: Tool neglects to dress Barney's tattoo after he completes it. Not something a professional tattoo artist would neglect to do, especially when he is tattooing a friend.
Suggested correction: Tool states that it's taken him several months to do the logo tattoo. It's also implied that he has done the rest of Barney's tattoo's. Barney, being the tough man he is, could have simply said in the past not to bother with dressing it and Tool has done as told against his better judgement.
