Guns and Occam’s Razor
The motive that will never be accepted. Occam’s Razor supports the validity of this but the disease that has grown to immense proportions in US society does not recognize logic or even reality. Any weapon purchased will be used. And, as mentioned, the use for which the weapon was designed dictates the most satisfying use. Sanity would and does limit this but the power and efficiency of current military weapons pushed this to the level of insanity. Las Vegas appears to be a trigger that simply could not be refused.
The answer is removal of these weapons from our communities. The fact that 90% of weapons are owned by 3% of the population should make this a problem for a noisy and dangerous but very tiny population. We already imprison nearly 1% of our population (.91%) we should be able to criminalize all military style weapons without that much disruption. The lives that will be saved, alone, justified this.
