There's no mental health practitioner who will claim to be able to predict future behavior after a single "check-up." Certainly not with the accuracy required to infringe on a fundamental right. That was a key, but little acknowledged by media or the anti-rights crowd, fact coming out of the Colorado theatre shooting testimony (and pretty much every other mass shooting situation).

Now, this particular guy had committed DV, was on the FBI's radar, and apparently his family and employer noted he seemed to be in mental distress, yet no one chose to use perfectly adequate -existing- law to get him an AS 47.30.700 examination which could lead to a disabling adjudication of mental deficiency with actual due process involved.

As in so many of these cases, if there is a failure it is not on gun rights proponents but on the people around the perpetrator who, with best of intentions to avoid labeling their loved one, let that concern stop them from acting in that individual's best interest.
