I don't see how you reach that conclusion unless you believe either that schizophrenics are just "making it up," or that mental health professionals make spurious and fictitious diagnoses. Oh, I suppose there's a third option - that the insane should be held responsible for their actions and imprisoned.
It's a toughie. I suffered depression for a few years in my 20's; and learnt it wasn't about "snapping out of it". Later, other family members have suffered - so I know a little of how mental illness works, though I'm no expert.
But, it's not hard to feign mental illness when the alternative is gaol.
Who knows what the Real Story is here. Sadly, I'm one of those cynics who thinks the worst in this kind of case. Thankfully, you (Liz) are one of the types of people who actually have to make tough decisions - not me. I have the luxury of sitting here making expansive (and probably ludicrous) claims whilst others have to make the decisions for real.
Ah well... back to the regression testing...
