Apparently psychiatry is composed of some of the worst kind of prostitutes. Any time there is a trial where mental condition is in question there is no problem finding experts who will, for a large fee, take either side. Seems that a lot of cases are decided by which "expert" is the best liar. Of course many cases are decided when one side can't afford the "care" of one of the industries "experts."
That kind of whoredom is not limited to psychiatry. M.D.s, lawyers et al practice it too - some, not all.
Money talks and B.S. walks.
