Goofs

At the command center, Espin's eye is swollen after his encounter with Jack Reacher. One scene later his eye is perfectly fine.

When they are still in the D.C. area, before they take a plane the New Orleans, they go to eat at Ted's Frostop restaurant, which is located in New Orleans.

The airliner Jack and Susan leave DC in is different from the one shown in-flight. The one taking off has podded engines under the wing. In-flight, the engines are mounted to the fuselage near the tail.

When Jack and Turner get into a cab near the Capitol Mall, there is no number on the trunk, but in a shot of the cab traveling along a street a few seconds later, there is a number on the trunk. Additionally the hubcaps are different between to 2 cars.

The first time Reacher and Espin meet, Espin's left hand changes from the outer to the inner part of the top of the car door when they switch between camera angles.

In the restaurant when Jack first confronts Colonel Moorcroft, the colonel is wearing MP insignia. He should be wearing Judge Advocate General insignia.

At the beginning, a local Sheriff and his Deputy are arrested for violating human trafficking laws on a "US Government base". They subsequently are arrested by a number of Military Police who come driving up to the diner in town. Military Police have no jurisdiction off-base in a case like this. The arrests would be made only after a Federal arrest warrant was issued and would normally be served by a US Marshall. However, any State or local law enforcement officer can conduct the arrest subsequent to the issue of a warrant. The Sheriff and his Deputy are civilians, so the MPs would have no authority off base regarding these officers.

No prison, federal or otherwise, allows anyone to have their firearms inside except guards during a riot. The MP who came to assist in the transfer of the major had his sidearm in its holster in her cell.

When reciting Reacher's military record, it says he was a Major, demoted to Captain and worked his way back to Major. Officers cannot be demoted in rank. Any crime sufficient to have warranted demotion would have resulted in a dismissal from the service.

After deplaning and while standing in the jet-way, Reacher simply pushes open the door that leads down to the access ramp so that all three of them can escape from their pursuers. This is a restricted access door, leading to the SIDA (Security Identification Display Area) of an airport. It is a limited access area and requires either an electronic access badge, or at a minimum, a code to allow access through the door. The door handle did have a keypad lock so should have been locked.

When Turner is choking out one pursuer in the alleyway with the hose, she wraps it one time around his neck. In the next shot, the hose is not wrapped around once, it is simply going in front.

The loop of hose around the back of his neck can barely be seen from the camera's angle. Just because the camera didn't see it, it is nonetheless there.

Susan says her agents in Afghanistan were shot in the back of the head, but in the flashbacks the male is shot in the back and when the female turns around she is shot in the chest. The second flashback is longer and the gunman finishes by shooting each soldier three more times each when they are on the ground, but this is off camera.

Turner initially says that the murdered MPs were shot with an "Army issue" 9mm. When the murder is shown, the shooter uses a Glock pistol. The US Army uses Beretta pistols.

While the shooter does use a Glock, there is a Glock model that fires the same Army issue 9mm caliber ammunition as the Beretta.

Jack pickpockets a man for his ID, and, presumably, Samantha used the stolen student's ID to board but no indication is shown on how Turner gets past security.

She likely also pickpocketed someone else, but it's not shown.

When Major Turner is checking her email at the internet cafe, she is on the Army Knowledge Online (AKO) website. In 2015 AKO discontinued its email service. All official military email is now done through Microsoft Outlook.

The year these events take place is not specified in the film. This sequel is based on book eighteen of the Jack Reacher series, while the first film was based on book nine, so unless specified, the audience do not know the year of events.

In the beginning, Reacher is in Washington D.C., and flowers are in full bloom, and the trees are all dark green with leaves. At the girls' school, the students are playing soccer in T-shirts and shorts. On the plane, a phone screen shows a call made "a week ago" on June 28, but just a day later they pass kids on the streets dressed in costumes for Halloween.

An aircraft that size requires at least 3 flight attendants, yet during the entire flight, there are none to be seen anywhere in the cabin, nor are there flight attendant seats visible that would allow for continuous visual observation of the passenger cabin, as is required by Federal regulations.

When hiding behind the MP car, Jack grabs its spotlight which has been shot away, and turns it toward the shooter, flexing 2 heavy wires by which it had been hanging from the car. But a through-pillar spotlight has no wires in its mount; it's electrically connected by the rod inside the shaft. So if the light head is separated in any way, the light won't work.

Col. Moorcroft hands Reacher a hard copy file during their second meeting. Reacher supposedly sticks the file effortlessly in the inside pocket of his jacket without folding it. That would never fit.

Towards the end, when Espin is escorting a crucial witness and is ambushed by Parasource members, his car's communication antenna is shot into pieces. A while later, Espin radios for assistance. It's essentially impossible to have sufficient radio contact without an antenna.

A scene set in Afghanistan shows a Search and Rescue (SAR) team arriving in a Vietnam-era UH-1 Huey helicopter. This type had long since been replaced by the UH-60 Blackhawk in front line deployable units of the U.S. Army and Air Force. The U.S Marines still have the Huey in service but not the model depicted in this film.

The aircraft shown in flight is a DC-9-10. No major carrier in the United States operates this type of aircraft any longer.

When The Hunter and his men are chasing Jack and Sam through the Halloween parade, there is a moment where one of the Hunter's goons speaks dialogue that is totally different from what he is mouthing.

In the Halloween Krewe of Boo parade, after The Hunter asks, "Did you see anything?", the lines "We searched the whole hotel. We didn't find a trace of her, nothing.", and his reply, "Well stop her", don't match what they're saying.

(at around 56 mins) When the protagonists run onto the airport tarmac, there is a shot of them filmed from inside the building though glass. The blacked-out camera dolly is reflected in the glass.

(at 1h 48 mins) When Sam goes into the coffee shop and the door closes behind her, the camera crew is visible in the reflection of the glass.

In the climactic chase through New Orleans, The Hunter jumps from a balcony and is seen landing on a cushioned pad.

When speaking with Sgt Leach, Reacher refers to her "DI" (Drill Instructor). The US Army uses the title Drill Sergeant, not Drill Instructor, a Marines term.

When Captain Espin is escorting Reacher through the prison, the Captain has his jacket unzipped. When wearing a jacket with a zipper or buttons, the jacket will be zipped or buttoned all the way up with the exception of the collar button. Any Captain would live this without a thought.

The two protagonists speak out loud of government top secret topics in a taxi when the driver can hear them speaking.
