Kanak, more or less shootings is relevant to the amount of humans willing to shoot another human being for a perceived justification and not necessarily the amount of guns available.  1 person, 10 guns, no grudges = no shooting.  1 person, 1 gun, 10 grudges, may equal 10 shootings.  A gun is not a disease, will not move from its given spot, will not bite, and has no corrupt intention of its own.
