Correction: Judge Lex does not ask Ma-Ma who the problem judge is, he knows it's Judge Dredd. He says it'll cost her a million credits and she questions this (she says "one million?") He is basically asking her do you know who Judge Dredd is and she says no, she does not know his reputation or what kind of judge he is, nor the extent of her problem. His reply is he does know who Judge Dredd is and that's why it's going to cost her one million credits.

Correction: Why wouldn't they have both done it? It must serve some sort of purpose, whether functional or symbolic. If one person finds cause to apply tape to their gun, it stands to reason several others would as well.

Correction: Yes, just like a real silencer. Silencers don't actually "silence" a weapon, they just make it very slightly quieter, like 15% or so. (The soft sound heard in most movies is very inaccurate). As the target, it's more difficult to judge how far away the weapon being fired is because you don't know if it's a distant weapon or a nearer but silenced weapon that's being shot at you, thereby making it more difficult to determine where to aim return fire. The guns sound the same to the viewing audience because there's not a lot of discernible difference on your TV between a sound that is 120 decibels (silenced gunfire) and a sound that is 140 decibels (normal gunfire) and we're always right next to the guns as they're being fired, not across the atrium with the villains being fired upon, so the effect would be almost totally lost on us anyway.

Correction: The display could not have been off since we only know the gun is empty because we can see the word "Empty" under the type of ammo Dredd has called up on the display. Any other angle in which it appears to be off is just because a bright blue light shining out of your gun in every direction isn't very tactical, so it's only visible from a very narrow angle; we have such technology now, so they certainly have it in this future world.
