Yep. I think the third does have an area where it could be applied that would make a difference. It can be abused but needs to be addressed. Mental health. There are too many people that are clearly not sane that cannot take care of themselves and endanger others.
Well, that's most of the Democrats, all of the Socialists, and a growing number of the GOP as well. At least the rest of us could have full employment, even if it is just distributing the Depends...
More seriously, this guy appeared outwardly sane as most from accounts of his behaviour that have been published. He had eccentricities which were attributed to gambling and having ample money to do so, a lifestyle many actually envy. There is only one account of him waking up screaming in the night, and virtually everyone has had a nightmare.
While there are those who are clearly
non compos mentis, and those who are quite obviously dangerously demented, many of these criminals spring from the woodwork without warning, and even those who give definite signs may be covered for (Jared Loughner comes to mind, who had a relative working for Law Enforcement). Medication may mimic the presence of mental issues as well, or even cause them, often as a side effect. One comes to mind (
Bextra) which I was given by a doctor for arthritis, but instead had me wanting to 'end it all'. Only the fact that everything was going better than ever gave me the presence of mind to realize it was a side effect of the drug and quit taking it. Had I had serious life issues and less mental awareness, I might not be here. To this day, I very rarely take anything stronger than aspirin, and even that (aspirin) not often.
So, the essential questions arise of who draws the line on sanity, and where? There are those who assert you'd have to be crazy to even want a firearm, much less to have several. OTOH, there are those who would assert you'd have to be crazy not to.
Currently, the US spends more money on "Mental Health" than any other category of health care. More than on Heart Disease, more than on cancer and treatments, more than on pulmonary disorders--or
any other class of medical expenses. Over $200 Billion a year, and yet, this man showed no outward sign of the transition from a 'fun guy' to a mass murderer.
I think we are left with the fact that some things cannot be prevented, nor even mitigated, not and retain any of our Liberty. Liberty does not come without risk. I caution, as has been done in the past
"Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety."
Benjamin Franklin
and what's more, will caution that they will have neither.
If we cross that Rubicon, beyond the current proscriptions on those who have been adjudicated mentally incompetent or insane, it would be difficult to overstate the peril to Liberty that would entail.
