I am quite the opposite. I have severe PTSD and social anxiety as well as bi-polar depression due to combat. I see my shrink every other month and my social worker therapist every other week. We have all talked at great length about my fears about having my guns taken away from me, and both told me there's no chance of that happening with me because I follow my medications and therapy requirements to the T. So, if veterans aren't seeking treatment, then it's their own faults when something happens and it's found out they have PTSD or something related from combat and aren't seeking treatment and the situation becomes worse for them. My doctor and therapist make sure to add in my notes that I'm not a danger to myself or anyone else.
Something along these lines happened to me last year, but in a child custody issue, not gun related. When my ex wife took off, out of spite she contacted my youngest son's mother and filled her full of a bunch of BS and lies, so in turn his mother withheld my summer visitation due to my 'mental health issues'. Well, a letter from my social worker and a court hearing discredited her as well as my ex's claims and in turn ended up doubling my visitation and giving his mother a hefty fine and contempt of court charge.
In a way I can see how the red flag laws could be useful, when not used for spite. But, I think it should be a professional of some sort...doctor, social worker, police, ambulance crew...who determines the need to remove the guns. If someone voices a concern, then have a professional step in to make the determination of if the guns need to be removed or not. Don't let some random person make an accusation and in turn have someone's house raided and guns removed without due process because of a grudge. Leave it up to a professional, not someone pissed off at someone.
