My husband experienced a terrible break-up at age 21. He was already somewhat abusing EtOH and had been under treatment for severe anxiety for 5 years (counselling & medication). His break-up caused him to do something stupid/suicidal in his mother's home.

He was taken to the ER & "in-voluntarily" committed to the mental health hospital for 72 hours. He was released without comment & never heard from any legal representative. That was 10 years ago or so. He was never notified about being banned from gun ownership or concealed carry. He does still suffer from anxiety and bouts of depression, but is in a stable relationship (with me ;-) and has learned coping mechanisms for when his anxiety builds beyond the norm.
He has since bought several guns going through the background check common here in KY. He has also applied for and received a Federal Firearms license approved by the ATF for his "hobby" of guns (his license is for the purchase & resale of "hobby guns" - those made prior to 1950 I think). We took our CCW course and he never thought of his "commitment" until he was given a denial notice. He has since turned in the requested paperwork, but their 20 days to give him a decision is long past. When he spoke to the office responsible he was given a bit of a runaround & told the legislators are trying to figure out how to change the laws and how that will affect his application.
My comment/question is that the above scenario should never have happened. Either he's banned from gun ownership or not for his mental break over 10 years ago. If he was cleared by ATF to buy and sell guns (that still work, not just dummy guns) and if he's cleared the background check several times, why wouldn't he also be able to carry a weapon?

Would anyone consider that he "lied" on his applications for his weapons and licenses when he never received notification that he should be banned?
I agree with what others have said that "mental health" is too ambiguious to do anyone any good. Although he is my husband & I am definitely biased, I do not think someone with a history like his is any more of a risk that someone like me who has suicidal ideations caused by certain medications. However, since I've never sought treatment for those ideations (except curtailing the use of those medication) my CCW was granted to me.
