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.
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.
Factual error: When Alex Montel gets into the police car and backs away really quick you see TJ get in the car and try to block him.

Answer: The SWAT Captain originally kicked Street and Gamble off the team and out of the SWAT Division completely for disobeying orders resulting in a hostage being shot. The SWAT Lieutenant convinced the Captain to keep the two officers in the division on a probationary basis to work back towards getting back on the team. Gamble was insulted by the probationary assignment and later resigned. The Captain offered Street the chance for immediate reinstatement to the team if he placed all blame on Gamble. When Street chose the probationary assignment over blaming Gamble or resigning alongside Gamble, everyone assumed Street cut some type of deal to remain in the SWAT Division without knowing the whole story.
