Factual error: After the cops respond to the domestic disturbance (son hitting mom), we see the male officer get in the back with the boy to show him the crime scene photos and he shuts the door after getting in. Police cars are designed so that the back doors must be opened from outside, however, he exited the car with no help. (00:21:00)
Suggested correction: Police cars just use the child safety lock on the side of door that prevents the back door being opened from inside. It's simple to turn them off so the doors can be opened from the inside.
Other mistake: When Emil gets out of the car before seeing Larry is dead, he is shown in the front of the car on the right hand side of the car. But the car is a left hand drive as shown when he gets back in. Who was driving? (01:08:20)
Suggested correction: You see him sitting on the right hand side the whole time, even when he first gets in and Larry says "new plan." He's reaching over with his left hand to steer as the car moves slowly through the streets. There's even a straight on shot around 1:03:15 and it's not a flipped shot since the license plate is normal. It could just be moving on its own momentum while in drive, or he's reached over with his foot, or both sides have pedals (like on a driver's ed car).
