Other mistake: After the scene shifts from Rico busting out of the black body bag to the street scene, as the camera pans down and to the left, water running off the shading panels of the camera moves along with it.
Other mistake: Dredd tells Judge Hershey that lethal range for bullets is 300 meters "you're safe" straight after people were being shot and wounded on the ground at that distance.
Suggested correction: Wounded, but not dead. He says they aren't lethal, he doesn't say they can't hit you though. His logic is that they can't be killed by the bullets so therefore they are safe.
lionheadPresumably the Judges also have body armour which will protect from extreme range and hence lower power bullets, which civilians wouldn't have.
Other mistake: As the transport rises and passes close to the lone guard, it's reflected in his visor. However, since it's close enough that the thrusters are billowing his cloak, the reflection should be bigger.
