Other mistake: When Barnes first gets into the Chevrolet Astra (blue car), he pursues the police car but never changes from first gear, as he has one hand on the steering wheel and the other holding his phone to his ear. Without a gear change he'd never reach chase speeds, plus the engine strain would be easily heard.
Continuity mistake: When the president is abducted in the ambulance there is a shot of him waking up. In the close-up of his face as he awakes, the metal nose clamps on his plastic oxygen mask are sticking straight out; when the camera angle changes the metal flaps are clamped down on his nose.
Other mistake: When the Secret Service agents are running after the Spanish cop, they are running and shouting with their weapons waving in the air, yet the group of Spanish police that they pass don't try to challenge them.
Character mistake: When Barnes is trying to describe what he saw, he awkwardly describes "something like a flash of light." A Secret Service agent would know that he had seen the muzzle flash from the gunshots. (00:17:40)
Character mistake: After Barnes rescues the President, he radios in his location as "seven blocks east of the plaza." This is meaningless on the limited-access highway where they are located. Barnes has an excellent grasp of the local geography and would give their precise location with specific landmarks. (01:21:20)
Character mistake: At the end of the movie the reporter says the lone assassin was shot and killed but the banner at the bottom says the lone assassin was arrested.
Continuity mistake: When the US Secret Service agents take the Spanish Police agent into custody before the explosion, the agent takes the Spanish Police agent's police badge off his belt and hands it to another US Secret Service agent. After the explosion the Spanish Police agent is seen running away from scene and his police badge is shown back on his belt. (00:27:00 - 00:30:00)
Character mistake: While talking to President Ashton, Phil McCollough comments, "We're looking for five people out of six million." Salamanca's population is only about 160,000.
Plot hole: It stretches credibility that the little girl wanders quite far away from the plaza and ends up on a busy road, and her mother just happens to be nearby.
Suggested correction: Anna wasn't following her mother. Her mother got separated from her in the chaos and when Howard carried her to safety, she saw a woman who resembled her mother leaving the plaza. She then ran in the general direction of the woman and it just so happened to be the same direction that Howard was running and ended up in.
Also, it isn't entirely out of the realm that her mother ran in the same direction as them both prior to Anna seeing her since she was out of the plaza before Anna and Howard were.
