Observations

Perusing the web, I notice
1. A quote from Fredrich Hayek from his early days as a student that pretty much every time the government passes a law to address some problem, the net effect is to make the problem worse.

Of course they do. If laws actually solved problems lawmakers would quickly find themselves surplus to society's needs. If the problem gets worse, then more laws are obviously needed along with bureaus to interpret them and collect fees. The surest route to success in government is to fail.

Hayek was speaking to laws governing economics, but the rule generally holds. Bear with me here.

John Fund in the National Review cites a paper by John Lott:

Lott offers a final damning statistic: “With just one single exception, the attack on congresswoman Gabrielle Giffords in Tucson in 2011, every public shooting since at least 1950 in the U.S. in which more than three people have been killed has taken place where citizens are not allowed to carry guns.”

Also noting that of the seven theaters showing the Batman movie within 20 minutes of the shooters home, the one he visited was the only one with "no guns" posted.

2. In that same vein, what is the correlation between tight gun laws and high murder rates? Chicago already has everything the Brady Bunch is now demanding and Nancy Pelosi is promising to offer for the nation as a whole. I checked and discovered that in the last year Chicago averaged some 42 murders a month, mostly gunshot, mostly black. This is the gun-free nirvana we're being set up for. Of course when it doesn't work, the obvious solution will be closer surveillance.Or Something.

So 42 black people a month is a statistic, but 27 white people in a year or two is a tragedy, to paraphrase papa Joe Stalin.

3. In the same article:

A lengthy study by Mother Jones magazine found that at least 38 of the 61 mass shooters in the past three decades “displayed signs of mental health problems prior to the killings.”

The word you're looking for here is deinstitutionalization. This involves closing down the state and privately owned minimum security homes for the moderately unstable and turning the lot of them out on the street where they are allowed to make their own decisions about their medications. Properly managed this could work out well for the nanny-staters. The Twinkies, instead of populating the busy intersections all day are now busy cutting out paper dolls with blunt-tipped scissors and their absentee ballots arrive at the front desk in a bundle where the staff can quickly and accurately fill them out and get them mailed in in a timely manner.
