Seeing what that aurora freak was warning of prior to his shrink - uuummmm - sorry - that dude does not and should not get a gun legally.
If there is a diagnosis that somebody is an immediate threat to themselves or others, they need to be locked up. At that point its not a matter of dickering of what civil rights they may or may not have, and firearms ownership should be among the least considerations. If somebody is going to be dangerous with a firearm due to psychosis, they are every bit as much a threat with a car, an axe, a chainsaw etc. and need to be committed.
