The single-minded — I would say obsessive — focus on gun control by the major media, in response to the recent tragedy at Newtown, is not thoughtful analysis. The issue is one of mental health, which includes a variety of factors, with guns being only one of a wide variety of inanimate and normally useful tools that can be used for deranged purposes (e.g. knives, hammers, poisons, fire, explosives, tire irons, golf clubs, baseball bats, automobiles, hands, feet, etc.).
Based on data from similar tragic incidents, an important factor could well be the misuse of psychotropic drugs. One of the most thorough reviews of this topic I have seen can be found here: “The giant, gaping hole in Sandy Hook reporting” by David Kupelian.
