Thanks a lot again for taking the time to fuel this discussion! After reading and rereading all comments here I'll try to generalize those findings. Once the number of weapons starts growing without proper control you hit a first threshold that ticks weapon deaths: two groups begin being significant, those that are armed and stupid and those that are armed and violent. If the number of weapons keeps growing you reach a second threshold, that boosts weapon related deaths by a lot: the group of people that are armed and violent and stupid starts being significant, a really dangerous subgroup. You can keep boosting this argument adding other kinds of people: desperate, psychos, stressed. Probably arming too much people that are stupid, desperate, violent and stressed... you end up with a big mess, like in some hotspots around some US cities.
