Continuity mistake: When Moreno is trying to get the border patrol cops to call for a helicopter, we see one has his arms around the other's neck, but in the next shot, his arms are around the other's waist.
Continuity mistake: In episode 6 - Once Bitten, Krieger is using the system, but has no training to do so. After Mallory berates him, Krieger states: "Yeah, I don't actually know how any of this works - that was the fat guy you killed". But the "fat guy" who does the satellite monitoring stuff doesn't die until this episode - a shock induced heart-attack after receiving a hard slap from Mallory.
Suggested correction: The episodes were aired out of order than what they were produced. "Coyote Lovely" was the 2nd episode of season 4 to be produced. So, as it was written, the fat guy dies before the events of "Once Bitten."
