That's good, because all the nut cases that shoot guns at people are receiving mental health care.
No, they're not. Sorry to burst your bubble, but in order to receive mental health services one must have private insurance or Medicaid. Neither is easy to get, although with reform the pre-existing condition clauses will eventually go away. How much actual help the mentally ill recieves will vary from plan to plan.
Anyone can receive mental health care for a $100.00 office visit at an urgent care medical facility. Once diagnosed, the physician on staff can prescribe anti-depressant drugs and the nut case is back on the street to do as they please with minimal follow up.
