Other mistake: Near the start, instead of showing bullet casings drop they show full bullets drop from the gun on the ground. (00:12:44)
Suggested correction: The shell casings appear to be unfired, but this is only because of the lighting and angle. Upon closer examination they are empty 5.56mm brass as they should be.
Continuity mistake: When driving the silver Audi A6 the first time, the version they are driving is a diesel, seen by the exhaust pipes facing down towards the ground with a bend. In the next shot they are driving the petrol version of the same A6, seen by the exhaust pipes holes facing directly out from the car. (01:18:33)
