It's sad on several levels. I've always struggled with the notion that certain mental states can render one not culpable of a crime they commit. Did he not do what he did? Isn't is generally understood that that kind of behavior is illegal. It's always better for the defendant when blame can be passed on to an inhibiting factor that exists in the turbulent nether regions of the transgressor mind.
It's terrible to lose a child as it's commonly cited as the worse thing a parent can experience. Such tramua can certainly bring on depression, which can lead to abnormal behavior, combine that with a cocktail of who knows what psychotropic drugs, and wierd things are gonna happen. It's very sad. But he still walked into a jewelry store and did what he did? Why that jewelry store and not a bank or a pawn shop? It dosen't matter becasue it was a crazy thing to do. Totally irrational but, not guilty?
