At 1:17, when Omar turns to inquire about the availability of Honey Nut Cheerios, the guard can be seen exiting the scene. In the next shot, at 1:19, the guard again exits the scene.
(at around 13 mins) When Omar is talking with Bunk, he says "I'll be seeing God long before I swear to him on the stand," but the DVD subtitles read, "Obviously a guy's alone before I swear to them on the stand." This has been corrected for the Blu-ray.
