The truth about guns is, apparently, a moving target.

…the literature on guns is just as messy as the statistics—often completely contradictory, with some studies showing convincing correlation between guns and homicide, while others equally convincingly show none. In the end, most of it shares an unfortunately quality: too much of the language implies causation or lack thereof between guns and death but only really shows varying levels of correlation.
