I don't see any evidence here he was "doped out of his mind.." No evidence here, and I haven't seen it anywhere. (We haven't even got to the stage of anyone involved in the legal proceedings admitting he was "out of his mind" yet, drugs or not, but that's another thing.)

From what I've read, the lawsuits have all been reported as being about the psychiatrist and the university not taking the steps to put him into an initial process of involuntary commitment, with the presumption that if that had been done, he might then have ended up being held until he wasn't showing signs of danger to others anymore.

Which in a way suggests nearly the opposite, that these people think that forcibly drugging him might have prevented it.

And there is such a common faith in psychiatric pharmacology being able to fix this sort of problem that there's a phrase to go with it, the "I was off my meds" excuse for doing something crazy.

Personally, I think there is a mistaken faith..As if once a delusional violent person gets the right drugs, that person will be normal and happy and will realize that they should keep taking those drugs. I think too many don't realize that it is rare for things to work out this way. That it's common for psychiatric patients, especially the severely ill ones, to be so miserable with the results of the drugs that they stop taking them once they are free of oversight..

I've been following the news on Holmes precisely because you're writing on these issues makes me more interested in knowing what his illness he thought she had and what drugs he was prescribed and whether he was taking them.. So far I haven't seen anything reported on that, haven't found anyone with proof of knowing anything about that leaking it.

In the process of looking for such info, I ran into this recent "I was off my meds" excuse, the NYC subway pusher:

Alleged Queens Subway Pusher Says She Was Off Her Meds, Namely Weed
By Adam Martin, Daily Intelligencer @ newyorker.com, Jan. 19, 2012

[..] She has some kind of a prescription she's supposed to take, but it makes her shaky and she prefers pot, she said. That day, she didn't have it, and she was in a bad mood. "I was homeless. I was hungry. I was fighting with my boyfriend. He came running up the stairs, and I just got up and pushed him." Menendez also wanted to clarify her hatred of Muslims and Hindus, who she says she's been "beating up ... for a long time" because of the 9/11 terrorist attacks: "I’m not mad about the people [who died]. I’m mad because I liked the buildings." With Menendez already deemed fit for trial, one does not envy this woman's defense lawyer.
 

Personally, I think it's highly likely, especially because he was a doctoral student in neuroscience, that Holmes was self-medicating, too, with disastrous effects. (It's ironic, but he himself could eventually end up suing the psychiatrist and university for not committing him.)

P.S. Here's another article, which in effect argues that many people with mental illness don't have a lot of faith in drugs making them better:

Please Take Away My Right to a Gun
By Wendy Button,  Op-Ed Contributor New York Times, January 18, 2013

She's a political speechwriter who suffers with severe recurrent depression, and writes about how after she had an incident with an intruder, she seriously considered buying a gun for protection,  then concludes:

.....The other day, the president and the vice president announced their plans to curb gun violence in the wake of the shooting in Newtown, Conn. I agree with all of their measures. But I believe they should be bolder and stop walking on eggshells about what to do with people like me and those not even close to being like me but still labeled with the crazy term “mentally ill.” The executive actions the president signed to increase access and treatment are all good, although the experts will struggle with confidentiality and privacy issues.

But since most people like me are more likely to harm ourselves than to turn into mass-murdering monsters, our leaders should do more to keep us safe from ourselves.

Please take away my Second Amendment right. Do more to help us protect ourselves because what’s most likely to wake me in the early hours isn’t a man’s body slamming at my door but depression, that raven, tapping, rapping, banging for relief.

I have a better chance of surviving if I never have the option of being able to pull the trigger.
