Wouldn't that mean that the people may only bear arms if they are in a well regulated condition while it's chaos out in our schools and in out streets. Sure seems we need more regulations for the security of the state.
I think that the wording isn't as arbitrary as orientalists try to paint it as.
The Amendment literally starts off stating
regulated militia, which is essentially the opposite of individual citizens carrying military-grade weaponry.
In fact, most people who want to keep the Amendment the way it is (including me) will agree that individual citizens shouldn't have tanks, SAMs, grenades, m249s, etc.
All that said, and the following already stated by myself, mass killings using guns are a symptom of a very sick society. The AR-15 platform is only as powerful as the munition you put through it. An AR-15 that fires a .22 LR is not an AR-15 that fires a 5.56 JHP. But a very sick person who feels as if he (and it's going to be a he 99.9% of the time) has no power is going to go out and get a cheap AR-15 that fires 5.56 in order to feel powerful, because our society is extremely dysfunctional.
Fixing the situation of first-world citizens trying to live in third-world economic situations would probably immediately curtail most of the symptoms/mass shootings that we suffer because of our broken and degrading society.
It's similar to the dysfunctional drug war, and addiction/organized crime. One perpetuates the other. Without drugs being nothing but an excuse for the power system to criminalize certain people, organized crime that centers around the black-market markup wouldn't exist.
-Disease: drug prohibition.
-Symptoms: organized crime, addiction, overdose, individual crime, privatized prisons and literal slave labor, corporate drug dealers with licenses by the state, corrupted doctors/healthcare system, drug-dealers selling antidotes to their drugs, increased healthcare costs for everyone else, etc., etc.
Of course, fixing either of those two problems requires more than a bumper sticker, and politicians who make themselves rich by continuing the status quo will fight any changes to the status quo, by whatever means necessary - with the help of the oligarchs who prefer the status quo.
To an oligarch or their politicians and police forces, losing a negligible amount of wealth and power is equivocal to losing all of their wealth and power...because people who are afraid of losing a negligible amount of wealth and power are the sickest people in our society, and are the ones writing the laws to keep the rest of us sick(er).
Luckily for the oligarchs, they are able to fund propaganda outlets d/b/a media sources, to have one half of the population fight the other half of the population trying to cure the disease, simply by throwing them random crumbs and empty platitudes that they themselves mock and laugh about in private. And as always, anything that the oligarchs are able to use for their own benefit, is a clear and present danger to society and everyone else who lives in it.
