I noticed that, too. You'd think something like giant fines and/or substantial jail sentences for reckless discharge would have more impact on the problem than this 1-5 blather. It suggests that they're interested in disarming the public, not preventing death or injury, doesn't it?
Fines or jail sentences don't work if you can't enforce them. Enforcing this kind of a penalty would require that police are sent to every wedding or celebration in southeast Turkey to check on people. The long term measures aim to bring people up so that they do not feel a need to shoot in the air when they are happy. Cheering or dancing should suffice.
