Being retired from a Veterans Administration Psych facility... I"ll offer this......
Adjudication is the key word regarding competency....
HR 2640 Section 101 (c)(.1)
(1) IN GENERAL- No department or agency of the Federal Government may provide to the Attorney General any record of an adjudication related to the mental health of a person or any commitment of a person to a mental institution if--
(A) the adjudication or commitment, respectively, has been set aside or expunged, or the person has otherwise been fully released or discharged from all mandatory treatment, supervision, or monitoring;
(B) the person has been found by a court, board, commission, or other lawful authority to no longer suffer from the mental health condition that was the basis of the adjudication or commitment, respectively, or has otherwise been found to be rehabilitated through any procedure available under law; or
(C) the adjudication or commitment, respectively, is based solely on a medical finding of disability, without an opportunity for a hearing by a court, board, commission, or other lawful authority, and the person has not been adjudicated as a mental defective consistent with section 922(g)(4) of title 18, United States Code, except that nothing in this section or any other provision of law shall prevent a Federal department or agency from providing to the Attorney General any record demonstrating that a person was adjudicated to be not guilty by reason of insanity, or based on lack of mental responsibility, or found incompetent to stand trial, in any criminal case or under the Uniform Code of Military Justice.
...and just for the hell of it.... I've been diagnosed with PTSD for over 20 years, and I buy guns at will.
Have there been specific cases where a Veteran had problems that should not have been? Certainly. Whose life has been perfect? With the massive influx of Veterans to the Veterans Administration Health Care System, some problems are likely to occur. Please refrain from knee-jerking in reacting to some highly provocative internet postings, that have surfaced in recent years.... and this one has been around for a while.
Get ALL THE DETAILS.... then grab yer tin-foil hats if you feel the need.
