"One side effect of universal background checks
No one seems to think emotional legislation through, ask what can go wrong, and how it can be prevented. So, suppose you're a woman who has been stalked, brutally raped and put into the hospital. Not only that, you don't know who attacked you and can provide no useful information to the police, because rapist used a mask, date-rape drug and/or blunt instrument to the head. You get out of the hospital, and not only is he still out there, but you are having terrible nightmares about it. You go to a psychiatrist for help, and start taking psychiatric medication to deal with the depression, anxiety and nightmares. And once you have healed physically, you start taking self-defense courses in both judo and firearms.
In the meantime, your stalker has plans for you. He starts phoning in anonymous tips that you have been making threats to any man who walks by. After all, you have been talking about buying a gun and defending yourself from attack. With a firearm, oh my. Which you can't effectively dispute, because you have largely withdrawn from society. The Police visit you asking questions. Or let's say that you tell your psychiatrist that you wish it was just all over with, without any specific plans to kill yourself.
Congratulations, under Oklahoma law you have now become a danger to yourself or others. Which the local thought police, otherwise known as the Community Outreach Psychiatric Emergency Services, are only too happy to certify. The police arrest you and drag you off to the local loony bin, the Tulsa Center for Behavioral Health, which is only too happy to certify that you are paranoid and delusional, can't look after yourself, and direly need their services. You decline to voluntarily commit yourself because you are the victim and have done nothing wrong. Which, unknown to you, ensures that you will be involuntarily committed.
Either way, your name will now pop up in a universal background check as "dangerously mentally ill". When you try to buy the firearm you have trained to use, you are denied and the police are alerted. And your stalker-rapist? Well, he has plans for you, and there's not a damn thing you can do about it to stop him. What are you going to do, call the police? After they carted you off to be certified as dangerously delusional? Just imagine how well that's going to work.
May you never find your self in this kind of situation."
