Ok, so someone is diagnosed with oppositional defiant disorder as a kid, can he get weapons when he's older? What is the definition of successful management in such a person? What if it's conduct disorder? Given the frequency with which people with these conditions have chronic lifelong problems, should they ever be allowed firearms? What if they've been diagnosed, but never actually violent? How about intermittent explosive disorder? Same deal? Well what about people without these disorders who make threats? Who determines how credible "violent threats" are?
What about someone with bipolar 1 or paranoid schizophrenia who has never actually been violent, but certainly has a higher risk of violent decompensation that someone who doesn't? Too risky for firearms?
How about someone diagnosed with early Parkinsonism? Maybe the tremors make handling firearms unsafe, or maybe we're worried they're developing Lewy Body Dementia and hallucinations could become an issue? What about other forms of dementia, frontotemporal dementia? At what stage should we lose firearms?
I could go on for hours (To Paladin's point).
Ok. I'm obviously not a psychologist or psychiatrist, but let's discuss. And it's not like I'm claiming this is a full proof plan, it's infallible, or not subject to additional information changing things. There's obviously a problem in our country with gun violence, glorification, etc...
First paragraph: are they allowed firearms now? Do we even screen or catch those disordered without noticeable signs? Answer is no. People aren't just randomly diagnosed with conduct disorders or ODD without a cause to even evaluate that person. With any of the examples, people aren't just randomly diagnosed.
If the individual can show that they can handle the responsibility that comes along with a machine designed to kill, then I'm ok with it. And that's something that is debateable, at what point is that. Not being a professional or trained psych*, I feel it's out of my depth to say.
Is that another irrational fear? That the state will misdiagnose people intentionally to reduce gun ownership below the estimated 1/4 of american ownership?
Next, the threats are credible because, as a society, we take people at their word. Mean what you say, say what you mean. People make threats, then there's consequences.
Next paragraph: bipolar 1: considering what the diagnosis entails, I would be very hesitant to issue a gun license to that person. Same goes for paranoid schizophrenic diagnosis. I don't think anyone with even the smallest bit of knowledge for these two issues would feel comfortable issuing gun licenses without more intensive vetting.
C'mon, Parkinson's? Why will they need a gun? Are they planning on joining the revolution? If someone in this scenario, which is terrible to begin with, has been as avid gun owner with no prior problems, I dont really see what the point of removing gun ownership would be.
But if someone with an end of life disease all of a sudden wants to own a gun, then again...very hesitant to the motivations.
You lose gun ownership when it's noticeable you're beginning to not really know what's going on around you. For anyone that's been involved with anything like that, they can attest it's not hard to notice.
