My only comments on the first paragraph are that I am well aware of the law but we are talking about Austin - so I have zero confidence that a trial will take place. And I have zero confidence that he would do much time behind bars if a trial were to take place. And if he were forced to take medications in prison then he would be fine in prison and wouldn't appear to be a danger to society.
The second paragraph didn't answer my concerns. A person on medication isn't dangerously insane. And we as a society aren't willing to put people in mental facilities for life if they don't want to be in one. So if a person is on the street taking their medication, society isn't at risk. As soon as an insane person gets off his medication then he is at risk. Unfortunately, insane people don't generally stay on their medications when they are away from people making them take their medications. So basically they are always at risk to society. How as a society do we address this basic flaw, a two strike rule, a three strike rule...? Don't just say that the problem is due to how we deal with mental health? Come up with a way to deal with it. Just saying allow the insane free psychology sessions or putting them in institutions for life without fully thinking out how that would work doesn't do any good.
