Continuity mistake: At the very end, as the S.W.A.T. truck pulls away and is driving through the desert after dropping off the prisoner, a call comes through the radio. Street puts his ear-piece on, the camera angle changes to Hondo who is right behind and replying to Street, and Street is again just beginning to put his ear-piece on.
Continuity mistake: When the S.W.A.T. team stops the escape attempt from the bus, the crime lord is seen getting out of the police car and walking towards the team. The camera angle changes and he is seen once again walking away from the car.
Chosen answer: Because he was offered a lot of money. $100 million is a lot of money to turn down for someone on a policeman's salary.
