Silverstrata: I’m completely with you when you say that secondary culpability needs to rooted out, and that dangerous madmen should be locked up. What I’m not sure about is whether you are also saying that the mentally ill are just as culpable as the sane. I’d have a little more trouble with that. Of course what I think is neither here or there, but as a passenger I would feel a whole lot safer if I knew that support was being provided to those who felt they needed it. My worry is that the stigma and/or treatment of people with depression or mental illness will prevent them from self-reporting.
