--snup--Dr. Siegel et. al. evaluated 10 different state-level gun laws for effectiveness. In no particular order, they were
Universal Background Checks. Individuals must undergo a background check to purchase any type of firearm, either at the point of purchase or through a license/permit application.
Violent Misdemeanor Laws. Prohibition of handgun ownership for individuals convicted of a violent misdemeanor punishable by less than 1 year in prison.
Handgun Possession Age Restriction. No possession of handguns until age 21.
Shall-Issue Laws. The licensing authority must issue a conceal-carry permit to an applicant unless they meet pre-established disqualifying factors.
Permitless Carry. Also known as Constitutional Carry. There is no requirement for a permit to conceal and carry a handgun in public.
Trafficking Prohibited. Also known as a straw purchase ban. No person may purchase a firearm with the intent to sell to a prohibited person.
Junk Gun Ban. Also known as a ban on “Saturday night specials.” A law prohibiting the sale of handguns meeting specific criteria such as drop testing, melting point testing, certain safety features, and/or an approved handguns roster.
Stand Your Ground. There is no duty to retreat from an attack in a public place where you have the right to be.
Assault Weapons Ban. A ban on “assault weapons,” usually patterned after the Federal Assault Weapons Ban of 1994-2004, which banned various cosmetic features on rifles.
Large Capacity Magazine Ban. Exactly what it sounds like, a ban on the sale (though not necessarily possession) of “large” (standard) capacity magazines.

In as clear of English as I can put it, this is what the authors found. Firstly, universal background checks correlated with a 14.9% reduction in overall homicide rates. Secondly, violent misdemeanor laws were correlated with an 18.1% reduction in homicide rates. Thirdly, shall-issue laws were associated with a 9% increase in homicide rates. This third finding, a 9% increase in homicide rates correlating with shall-issue laws, is the weakest of the three in terms of supporting evidence from other publications. Numerous other studies have both supported and disagreed with the notion that shall-issue increases homicide rates, something the authors mention in the paper.
Further, it’s interesting what the authors did not find. The authors found no correlation between overall homicide rates and any other law in the study. Not assault weapons bans, or magazine-capacity limits were shown to have a measurable correlation with homicide rates.
Interestingly, the study found that bans on “junk guns” were associated with slightly lower (6.4%) suicide rates, and permitless carry laws with modestly higher (5.1%) suicide rates. Both of those findings, however, failed the author’s falsification test. A falsification test is an effort to make sure that there isn’t some external X factor influencing the data. Both findings were shown to have a similar correlation with the non-firearm suicide rate, not just the overall suicide rate. Since these failed the falsification test, they were excluded from the final conclusion.
This is getting to the answer.
We'll find a link to the actual data.
