This is the first time someone has asked me this at HPD. The question that the officer asked is what is on the mental health questionnaire form that we fill out every time we go and apply for permits there. There is also a form asking for my medical/health provider. Why should they need more proof? Has anyone active, retired or former military have been asked this by the workers at the firearms section, and to provide proof?
The forms/waivers are all you're required to provide. So if they ask (which I have been), just say what I did: "Ask my doctor, I'm not a medical professional and not qualified to make that diagnosis."
I think you might have misheard or he misspoke about a call...They call doctors for clarification, not the applicant. It's nothing to worry about, anyone with PTSD and has been treated can have their doctor change it to "stress fatigue".
yeah, bad enough the line is too long, now uniformed officers are asking ?'s that is none of their business, thats y i don't put my VA doc on the forms, i just used my civi. doctor i used once to get out of work 
Actually it (kind of) is, if they're asking as part of the mental health/background check. I strongly doubt some random officer is trolling the line to disqualify applicants. It's more likely that they're doing some "pre-screening" to expedite the process and assisting/weeding out those who don't have required docs, active TRO's, etc.
But you're right about who to list on the forms, I don't ever put the VA or any specific doctor...I'm very generic in putting Tripler Army Medical Center*. My cousin who never gets sick listed his urologist. I guess until they make erectile dysfunction or VD a disqualifier, he should be okay.
Google "Veterans Disarmament Act". You will find lots of information. This is only one of the pages dedicated to it.

Calling HB 2640, the "Veterans Disarmament Act" just makes it sound more ominious that it actually is. Keep in mind that the PTSD disqualification applies equally to all citizens diagnosed and not just veterans. But it makes no difference in Hawaii, because mental health checks have been required for years.
