Factual error: The very first shot of the movie takes place in Chandler, Arizona. However, the mountains seen in the distance, over the hills, are the Sandia Mountains which are in New Mexico, near Albuquerque. (00:01:00)
Factual error: At the beginning when Kate enters the bedroom and is shot at, the hole made by the shotgun could only be made by slug ammunition, but you see buckshot around the hole. Buckshot at that range of about 12 to 15 ft. would not have made a center hole anywhere near that size. (00:03:20)
Factual error: When the forensic crime scene investigator is asked how many bodies are in the house he states that they have not checked the attic or crawl space. The house is built on a slab foundation and would not have any crawl spaces. Easy mistake for a writer to make if they never lived in the southwest where such construction methods are employed. (00:05:30)
Suggested correction: Some houses in the southwestern US are built with crawl spaces, especially in areas on or near rugged terrain (as shown in the beginning of the movie). Also, it's possible the cartel dug in a crawl space to create extra room to hide more bodies.
Factual error: When Forsing moves his hand to unlock the door, the bolt on the weapon is in the open position. AR/M are fired from the closed bolt position. (00:35:25)
Factual error: The tunnel into Mexico is described as being near Sasabe, stated as being east of Nogales. In reality, Sasabe is west of Nogales. (00:51:20)
Factual error: At the beginning when Kate kicks in the door to the bedroom it swings the wrong way, A door for a room in that configuration would swing towards the the other wall, not giving up 3 feet of swing dead space and making for an awkward entry. (02:42:00)
Factual error: Kate is said to have been on the FBI SWAT team since day one, and therefore has never worked a case from behind a desk. However, FBI SWAT teams are composed of regular field agents who respond to tactical scenarios only as needed, and otherwise carry out normal investigative duties. Unless this is the most overworked SWAT team in history, Kate would certainly have handled at least a few cases from a non-tactical perspective.
Factual error: In Juárez, the Mexican police are wearing vests with "Polícia Federal." The actual spelling should be "Policía Federal." "Polícia Federal" is Portuguese. "Policía Federal" is Spanish. The vests used in the movie are Brazilian, not Mexican.
Factual error: During the briefing before El Paso a group of men were introduced as "Delta." There were not "Delta" due to a couple of items: 1) They were using single point slings, that's a S.E.A.L. thing. Delta prefer to use two point slings. 2) Their sidearms were SIG P226, another S.E.A.L. thing. 3) Their dropleg holsters were way lower than Delta prefers theirs.
Factual error: When Blunt enters the room and is shot at, she stitches the guy with a full auto burst. If you are doing a hostage rescue, you don't have your weapon on full auto.
Factual error: At the tunnel scene you see the "Delta" members using the single tube N.V.G. Delta has been using the standard binocular type for years now.
Factual error: The lightbars seen on the Mexican Federal Police trucks in Juárez are incorrect - they show both red and blue lights to the front, but actual MFP vehicles show only reds to the front. Also the uniform vests are in Portuguese, not Spanish - the accent is on the wrong "i."
