Depending on the personality type and severity it can be treatable. The article was ambiguous with 'personality disorders' and included diagnoses such as "rageful personality" (treatable) and "depressive personality" (treatable). While many personality disorders may not be treatable, severe cases of certain disorders like paranoid PD, which may actually be misclassified cases of other disorders (especially 30-40 years ago), can certainly be minimized to help the individual lead a more functional life. As you said, in many cases it's just a part of their psyche which can potentially be controlled if the right motivation and tools are accessible.
Even if you think that's total bs, 22% is not an insignificant number. Going off the sited study, that's over 100 people who may still be alive instead of murdered because someone's mental illness (either severe depression or psychosis) wasn't recognized. I'm not trying to say mental illness is the only cause of mass shootings, or even the main one. But to say that making a point of mental health's role is a cop out is just like brushing the issue under the rug, which is disappointing to hear from someone hoping to go into psych.
Those aren't recognized personality disorders. As to treatment, I'm going by the actual guidelines for treatment of real personality disorders, of which the only treatable one is BPD. That you take the public's view of this as an issue of mental illness shows how little you have read from actual forensic psychiatrists and psychiatric experts in the field. I've actually studied the subject pretty thoroughly, and agree with the majority expert opinion (rather than the political talking point) that, and I quote:
"It would be ridiculous to hope that doing something about the mental health system will stop these mass murders," said Michael Stone, a forensic psychiatrist at the Columbia College of Physicians and Surgeons and author of "The Anatomy of Evil," which examines the personalities of brutal killers. "It's really folly."
"I think it's the human inclination to explain behavior that is frightening and tragic as the result of mental illness because it's very hard to understand that individuals do not have to be mentally ill to do something frightening and tragic," said J. Reid Meloy, a forensic psychiatry professor at the University of California at San Diego who studies mass killings and consults with the FBI.
How could a system be devised to triangulate the risk and identify real threats? Not easily. Or ever.
"From a psychiatric perspective," Gold said, "I don't think you can design an intervention to prevent mass shootings."

The public wants to believe these people have diagnosable and treatable mental illnesses, but I've never read an expert opinion to that effect. That is where the disconnect with the public comes in- they think these guys are disconnected from reality, delusional in some way. But in reality, they have the same personality type as any garden variety killer- they aren't any different from some gang member in Mexico that murdered half a dozen people to for and buried them in shallow graves. It's the same personality traits that cluster in these people- antisocial, paranoid, borderline, often with a degree of narcissism. But these traits are also present in a great number of the healthy public. Surgeons, for instance, often possess the same cluster of traits that make people think these killers are defective individuals, yet function extremely well and productively for society. That is why people in the forensics field laugh when others say mental illness is at the root of these crimes- these guys generally possess psychological profiles that are variants of normal, and if you wanted to watch everyone that had them, good be watching damn near a quarter of society. It also infantilizes violence, because nothing separates most mass shooters from ordinary murderers on a psychiatric profile, yet you don't see the public trying to claim every murder in the inner city is precipitated by mental illness.
I don't believe we should be stigmatizing the mentally ill by associating those with personality disorders, which are by definition not forms of mental illness, with them. That's how we ended up with a society that has a widespread fear of schizophrenics, despite the fact that they are less likely to harm a member of the public than vice versa. The public has grappled with tragedy they don't understand by lumping it with a group of people that are misunderstood because that is convenient for them, because the idea that these people were fundamentally broken on a psychological level that merely needed treatment is comforting, because it gives them hope that by throwing money in a direction they can fix things. That's not reality though, and I've never read a single expert report or research paper from a forensic psychiatrist claiming otherwise.
Thanks for the Bernett in regard to psychiatry though. It just goes to show how little must people actually understand about mental illness that you would say as much, when every expert in the field is actually on my side in regard to the issue. The issues you would want to fight are so widespread that the only solution would be Big Brother style monitoring of virtually everyone, because there aren't many people that don't possess a trait or two that could give them a tendency toward violence. 1% of the public has psychopathic/antisocial personality disorder, do you just want them all on therapy forever even though no therapy is proven to work and most of them aren't and never will be criminals just in case? Do you want the one in ten Americans with severe anger issues forced into treatment as well, despite the fact that most of them will never commit a violent offense in their life and don't want treatment? Should we monitor all of the 6% of people with BPD and throw them on intensive therapy every time their behavior sets off red flags?
I could keep going, but the thing is, you're looking to treat a very, very large percent of the population, most of which do not have any over signs of true mental illness, in the hopes that we can catch the one in a million that ends up being a mass shooter. It's invasive. It's impractical. It can't work. And it is a cop out of a solution thrown about by politicians looking to blame anything but guns. So they blame the one group that doesn't have anybody living for them- individuals with mental illness.
