Other mistake: When Bogomil gets shot two bullets are fired, one by the drive-by shooter and one by Karla, yet there are three distinct bullet holes and a forth large hole in the rear windshield of Bogomil's car. Two holes are completely unaccounted for. (None of the windshield holes are tree reflections.)
Continuity mistake: When Axel walks away from the receptionist in the Shooting Club with the bag of vitamins, in the close up he has his left hand below the bag, and holds the top with his right hand. But in the next shot he's suddenly let go with his left hand and only holds it from below with his right.

Factual error: Ronnie Cox is shot in the heart at point blank range by Brigitte Neilsen, and it looks to me like she's using a large caliber handgun. Keeping track of the action of the film tells us that Cox is sitting up in bed chatting to his friends just three days later. What nonsense. Even if he did survive (unlikely) he'd still be in Post-Op Intensive Care at that stage. He wouldn't be conscious, let alone allowed visitors.
Continuity mistake: After being put on leave, Bogomil leaves the office and is driving towards the camera. His car is being followed, then passed by, the Mercedes Benz driven by Karla Fry. The license plate on the front of Bogomil's car is 2CTE919. When he pulls over to help Karla the license plate on the front of his car has changed to 2CTE673.
