If numerous emitters were placed about a building, and each was programmed to blast a cloud of thick dense smoke whenever a gunshot was detected in close proximity, a shooter would be doused in fog and unable to aim. People not caught up in the fog may be better able to escape. People caught up in the fog with the shooter would be on equal footing.

       I tend to think they should be breakaway smoke cannisters which you can throw, thereby blinding everyone but yourself. Arguably the gunman might try to use them too. [+]

       You didn't indicate that the inky cloud might mark the shooter for later identification and arrest. If the walls were lined with sensor-triggered ink-mist sprayers, then the shooter would be the one getting the MOST inky stains....

       Good call [Vernon]. Others marked would be persons of interest for witness testimony.

       I imagine these events are rather chaotic. The only person who knows what is going on is the shooter. This essentially takes away that advantage by adding more chaos to their world, and removing some from everyone else. Hearing a gunshot is one thing, but hearing a gunshot and seeing a cloud that tells you where the shot was fired is another.

       Yes, I can see that a blinded gunman is much safer than a seeing one.

       Oddly yes. Even if he's just spraying off shots, they aren't directed at a target.
