Continuity: When Beck is shot outside the Precinct, from the front view he has no exit wound on his forehead. Yet when he lands on the snow a few seconds later, an exit wound has appeared.

Factual error: In the shot where the laser sights of the assailants come in through the windows and holes in the wall, their angles are far too different from each other. The shooters are standing at a rather great distance from the structure and at more or less the same height. All the laser sights should have more or less the same direction and certainly not make a sweeping motion inside the room.
