Plot hole: Alex Montel is arrested and then held because his identity cannot be confirmed. This is not a valid reason to hold him, unless he is a terror risk which is never mentioned and the FBI are not involved. His expensive lawyer should have got him out on a bond with no issue at all.
Factual error: In the scene where the Learjet takes off the jet starts to roll. Then there is the shooting with the SWAT team, towards the end of the shooting the pilot pushes the power levers forward to accelerate. Regarding the short take off run they had on the bridge, the pilot would have stayed on the brakes until the engines were at full thrust, then released the brakes, started rolling and wouldn't touch the power levers until after liftoff or in emergency.
Continuity mistake: During the bus scene TJ stops Montel from getting away by crashing the beige car into the cop car that Montel tried driving away in. When he does this the beige car drives into the intersection crashing into a blue car. Then the angle changes and shows the beige car undamaged but the blue car was damaged.
Continuity mistake: When Montel is in the restaurant with his uncle, he lays the knife on the table on its side with the blade facing him. In the next shot, without anyone touching the knife, the blade edge is facing up pointed at the uncle. (00:34:25)
Continuity mistake: After the scene were the helicopter is shot down by the sniper we see a large piece of the helicopter (possibly a piece of the rotor) dislodge and get stuck in the side of an air vent. Then shot changes to show the copter crash into the street below. When the shot changes back to show the S.W.A.T members getting up there is a clear shot of the air vent with no piece of metal sticking out of it. (01:12:05)
Factual error: In the bus escape scene, when the fake police man enters the bus and shoots the busdriver in the head, the bullet makes a hole in the window but there is no blood. If a bullet exits the head so close to the glass you would see something on the glass.
Continuity mistake: During the verbal fight between Gamble and Street after the bank incident, Gamble grabs Street and slams his head into the mirror and you see glass in Street's hair from the reflection, but when the camera changes to a view of the back of Street's head, you see no glass. (00:12:55)
Visible crew/equipment: In the scene where Sam Jackson and Colin Farrell are stopped from escaping the subway tunnel at a locked gate, they get the idea to blow the lock with explosives but there is a visible, unexplained string extending from the lock as it is used to create the effect of the lock being blown off.
Other mistake: In the scene where LL catches up to the suspect running from him, it is obvious that LL never really puts the handcuffs on the suspect. You can hear the noise but he is not being cuffed.
Visible crew/equipment: When the SWAT team members back away from the bank after dropping off the secure phone, the camera's shadow is seen on the shield that one of the team is using.
