How many people has alcohol killed? Or cars/vehicles? Or string, neckties, fishing line, and a host of other ligatures? Or bathtubs and toilets? Do we ban those, too? Where do you stop? All of those have been used to kill other people, just as guns have.
The problem isn't with the guns. It's with the people with their fingers on the triggers.
You cannot legislate evil. Evil will always find a way. Cain used a club. Derrick Todd Lee used a knife (Baton Rouge serial killer). Ted Kaczynski used bombs. Do you think that banning guns would make those victims happy?
It really gets frustrating when people continue to take the blame off a human and put it on an inanimate object. No one wants to offend someone, and many want to make sad little sob stories to defend the scum that are responsible for the violence. It's easier to sue gun manufacturers and blame the gun for the damage.
I've held and shot a lot of guns in my lifetime, from pistols to hunting rifles to an AK-47 and SKS. Never, not once, did I injure someone, much less kill another human being.
As for spitting on the theory that more trained people carrying guns would deter some crime, well, more power to you. The subject of schools and their amazing lack of security has been a subject discussion between me and others a lot the past 2 years. I, for one, don't have a doubt, that if a school had 2 armed police officers patrolling the school during school hours, a criminal would definitely think twice before attempting or actually carrying out an attack. Feel free to disagree. But those people are cowards. They don't want someone else to kill them first.
