I have a friend who is schizophrenic. He was denied a permit based on his disorder, he is only the second person I know who has been denied a permit.
I added this to the thread just to illustrate a situation where mental illness resulted in a denial. I don't know all the details but his care was not mandated by the state, however I believe no doctor would submit proof that he is not a threat to himself or others.
If treatment was not mandated by the court and it was dealt with through medical only, there is no reason in the world for it to have become public information other than his own ignorance or an illegal privacy invasion. It just doesn't pay to tell everything you know.
We're from the government and we're here to help!
