So far, I've had a few defendants that were found NGRI but when under my care, my opinion was it was truly drug-induced psychosis. Again, that does not afford legal defense. The court's opinion, and this went all the way up to the Supreme Court, was that if you're under the influence of substances (e.g. you got drunk and shot up someone's house), too bad. You shouldn't have gotten drunk, you damn well knew you could've done something stupid while drunk but let yourself do it, and you will suffer the consequences.
The only exception to this is if the person was intoxicated because someone forced them to be (Ever see North by Northwest ?), or if the person's intoxication was the result of a medication where the person was not given sufficient warning that they could have done something dangerous as a result of the medication. (e.g. the person is put on Ultram, gets a seizure from the Ultram, and during the seizure ends up kicking someone, and yes I've actually seen that happen for real.)
I've seen the doctor's report where they reported the person was psychotic or manic and never once ever touched upon the possibility that the episode was drug induced.
There's also plenty of people who, while drunk or high, do dangerous things, and are now in a forensic setting. When doing a risk for future violence, the conclusion is the person will be fine, only so long as they remain sober, but then what is the chances that'll happen?
These are just a few cases where the combined fellowship could be a major factor, and if it's a big big case, you could be the first guy the lawyers want to hire as an expert witness.
I'll likely not be at San Diego. The wife's due for a child and I ought to be home with her!
