Continuity mistake: Longmire is taping prisoner photos to the wall. When looking at the last photo, the tape is in the middle of the paper. When he puts it on the wall, the tape is on the right side of the paper. When the photo is in the background, the tape is on the left side. (00:59:55)

Trivia: On the marquee they are showing "The Highwayman" (which could be one of several films). In 2016, the same year this episode aired, Craig Johnson published "The Highwayman: A Longmire Story." Incidentally, Netflix is distributing an upcoming film called "The Highwaymen." And, Callum Keith Rennie, who played Walker Browning in "Longmire", appeared in the 2000 "The Highwayman" film.
