I don’t think eliminating guns or restricting the types of guns people have will do anything to stop mass violence at schools. If kids can’t get their hands on guns, they will borrow a car and drive it into the lines of children waiting for buses.
Did you know that in 2017 more than 40,000 people died in automobiles in the US, and over 15,000 died from firearms, most of those suicide? In fact in 2017 the total fatalities for mass shootings was 344 according to this website: Bulletin: Gun Deaths Increased in 2017, Gun Violence Archive Data Show
Why is there no outrage over automobile use? Probably because almost every American uses an automobile, but not every American owns firearms. But in terms of numbers, guns account for relatively few premeditated deaths. Personally I do not see the value in eroding the 2A on such a basis.
The 2A exists for a reason. I find in my conversations with people it really boils down to if you trust the government or not. Many gun owners do not trust the government and therefore wish to partake in the 2A, which was created for the very purpose of staving off tyranny. And before anyone enters the argument with, “But the government has drones and air power!” Well, the US had vastly superior air power in Vietnam, too, but we lost. The US was literally evacuating Saigon as the NVA rolled in. Within a week of the US pulling out of Vietnam the south’s government fell and the country became communist. Overwhelming firepower does not always win, quite often pure numbers wins. Also the very fact that many Americans do own guns means that they can storm Army Depots or National Guard outposts to secure more guns, tanks, etc. That is what the 2A grants us. Ask yourself how much you really trust the US government right now. Is it worth destroying the final line that is the 2A for less than ~15000 gun related homicides a year? Personally I’m not convinced that it is.
Once one kid uses a car to conduct mass violence at a bus stop they will prove that taking away guns is/was nothing short of masturbatory. Not to mention many proposed gun laws are quite ignorant to gun ownership facts. One example: “high” capacity mags can be 3D printed now, so eliminating the ability to purchase them legally only means that anyone who wishes to have a high capacity mag can manufacture one, which means that only law-abiding citizens will follow the law anyway. Such a law is worthless. Did you know that you can purchase something called an 80% lower, which is an AR-15/10 receiver that does not have to be registered or sold through a licensed firearm dealer? That’s because, according to the law, it is not yet a firearm because 20% of it has yet to be milled. Enthusiasts can purchase 80% lowers, mill the other 20% out, and have themselves a lower receiver. It has no serial number, requires no background check, and comes with no bill of sale from an FFL. These 80% lowers can also be 3D printed. In short: you simply cannot restrict people from manufacturing anything as “simple” as a lower receiver. That would be like trying to make it illegal for people to make their own clothing.
Many of these school shootings are conducted using weapons that kids obtained from their parents, or purchased from civilians and not licensed firearm dealers (such as in the case of Columbine). Inhibiting the sale of guns and types of guns will not stop mass shootings at schools. It might stop one or two, I’ll grant you. But again, was that worth the erosion of the 2A? Personally, I’m still not convinced it would be worth it.
Right now you have to be 21 to own a handgun. I would support legislation that required citizens to be 21 to own any semi-auto firearm. Any hobby follows a progression; most children start with .22 rifles, then make their way up. Most parents buy their high schooler a used sedan, not a brand new sports car. Gun ownership should be looked at in the same way, an 18yo maybe should not be purchasing an AR-15 as a first gun. I would also support legislation that mandated a gun-safety class be taken upon purchasing your first firearm, much in the same way people need a driver’s license, or they need to become endorsed for motorcycle riding. Gun-safety classes would be a good source of revenue for local municipals, and they would provide a strong barrier against misuse of gun ownership since it would be another way to flag offenders.
In closing I think most suggestions to limit the sales of guns would do nothing to curb violence and I think people wishing to conduct mass murder would find other means. When Timothy McVeigh murdered 168 people and injured over 600 others, we didn’t blame the fertilizer that he used, we blamed him. Why is it different with firearms? I do support holding parents accountable for not locking up their guns and I do support age restrictions and mandatory gun-safety classes, but trying to eliminate the types of guns people have access to won’t do a damn thing in preventing mass murder.
