Robb, I don't do ANY criminal forensic work. I keep my criminal activities limited to my own time. As a clinician who has been in active practice for >25years... I think the MPD diagnosis and defense is BS. I think I'm in the majority, but there are some "experts" who make a great living on the defense side of that question.<br> Re: the idea that screening would be simpler in the general population of folks than in the "jackass" population... actually, the OPPOSITE is true. On the carry permit issue, for instance, the "base rate" in society for carry permit holders to actually use the weapon in a criminal endeavor is so low that "prediction statistics" fail. To oversimplify - the "target event" (criminal use of a handgun) has to occur with a high enough base frequency in the population being tested. <br><br>Enough of that academic stuff... just don't you pay your hard earned $$$$$ for any mope who says he can do that kind of evaluation for you with any accuracy!!
