I suspect the real issue here is mental illness. State public mental health systems tend to be an underfunded patchwork. On a Federal level, SAMHSA divides its focus between mental illness and substance abuse and many states follow suit. Although the two have some connection I never understood combining these two into single agencies. IMO it is indicative of an overall half-assed approach to both. I will be interested to see the future reportage of Adam Lanza's mental health issues. The usual bureaucratic mantra is to decry "gaps in services". OTOH the taxpayers don't want to pay to fill those gaps. And the cycle continues.
