With the way things are going here in Kali, I would suggest the following. IF your friend thinks that there is a possibility that he will be denied, I would say that that person is better off not trying. The following things will cause a denial:
Admission into a mental health institution
Probation or Parole status - will also confer an immediate call to his P.O.
I believe that even a misdemeanor domestic violence complaint will cause the wrath of the DOJ
Restraining order taken out
Warning, as of new January 2003 gun laws, mental institutions and therapists are required to report to the DOJ patients that they suspect of being capable of any type of violence, and what they are being treated for. This also applies to patients who voluntarily come in for consultation. This technically is supposed to only be used in cases where the therapist believes the patient to be a threat, so that it can be used to deny that person when applying to purchase a firearm, but come on. Just imagine what would happen if a patient whom the shrink did NOT report went out and shot his girlfriend, or robbed a place at gunpoint, or committed some other type of crime with a gun. Given this scenario, I imagine that shrinks will be reporting any and all patients just to keep their noses clean.
If your friend is currently being treated for some type of anger management problem or other type of problem involving the potential for losing his cool, he might want to ask his therapist if the shrink has reported him, I believe that if asked, the shrink has to tell you.
I imagine that it will take a long time, perhaps years, to get this up and running, so for now, this should be in the clear, but hey, who knows. Kali just sucks in this arena, who knows what they are going to come up with next.
