Lets pretend for a minute that the so-called "assault weapons" used in the massacre were in fact banned and had been wiped completely off the face of the earth.
Adam Larza could have walked into that school armed instead with a pair of "old-fashioned" .357 revolvers, a couple of speedloaders for them, and a vintage Winchester Model of 1894 lever-action 30/30 deer rifle with a few extra shells in his pocket.....and the outcome of the massacre would have been EXACTLY the same.
When you are a lunatic with a premeditated intention to commit mass murder in a "gun free zone" against victims who you KNOW will be unarmed....it doesnt really matter what sort of guns you use or how many bullets they hold.
The way you prevent massacres is not by inventing silly, feel-good laws about guns that (a) dont make a difference and (b) wont be obeyed by criminals in the first place. The way you prevent massacres...is by making sure that would-be victims have the means to fight back.
This is a ridiculous comparision, and to say it would turn out the same is pure ignorance at best. There are fundamental differences between the guns you mention and the actions required to fire them.
The gaps in time alone in changing weapons could be enough to allow people to run away or move to cover.
What I find more interesting is your situation.
People with dependancy issues usually transfer that dependancy to other things. Addictive personalities will always justify the need or use of things to feel good about themselves.
Some justify alcohol, some justify drugs ( both legal or illegal ), some justify guns.
People who are addicted to substances often replace that addiction to other things, like women, rage, hoarding and guns.
Either way, attempting to justify homocides by demonstrating that something could cause the same damage only shows the lack of compassion for the dead children who end up victims of paranoid people.
School shootings are far from over. There are plenty of gun nuts right now building stockpiles of weapons and ammo, camoflauge, gas grenades, armor and planning the next mass killing.
Are they mentally unstable?
No, not really, they are just victims of propaganda blasted at them by right wing sources until they realize they are going to be the ones to start the great revolution and gun battles all the gun freaks are waiting for.
Doomsday preppers is chockful of morons with outrageous thoughts and moreover, serious weapons for a fight they can only pray happens in their lifetimes in order to feel justified.
Unfortunately, that great fight isnt coming anytime soon, and they will all end up killing each other.
Thats how the brain works in the Gun mindset.
