Not the gun." His claim, a twist on the gun-rights adage that \u201cGuns don\u2019t kill people, people kill people,\u201d is a popular refrain, with little evidentiary basis.<\/p>\n Joseph Pomianowski is a Yale Law School graduate and conducts research at the Polish Academy of Sciences. Ling Liang Dong is a recent Yale University graduate and currently conducts research at Microsoft Research NYC.<\/p>\n A 2013 Gallup poll<\/a> found that almost half of respondents viewed mental illness as \u201ca great deal to blame\u201d for mass shootings, although there is no data to support a causal link between mental illness and gun violence. Fewer respondents blamed other factors like gun access, despite the fact that limiting access has a well-established, strong correlation with reduced gun accidents and deaths. More recent polls<\/a> have revealed that similarly uninformed sentiments<\/a> remain.<\/p>\n Frustrated by the sparse studies on the subject, we dug into the data from 22 unique gun law policies from the last decade to see which show the strongest correlation with gun injuries and deaths. To measure the strengths of each law, we used data on state gun policies provided by the Giffords Law Center and fatal injury statistics from the Centers for Disease Control\u2019s web-based Injury Statistics Query and Reporting System.<\/p>\n For each gun policy, we ran two separate tests. First we calculated the simple pairwise correlations between the strength of a policy in a given yea and corresponding fatal injury outcomes from the following year. Consistent with past research<\/a>, we found that although mental health reporting laws are weakly associated with lower suicide rates, they showed no correlation with homicide rates. Decreases in fatal injuries were most strongly correlated with gun-access and gun-use restrictions, such as owner licensing requirements, gun dealer regulations, and local regulations that allow municipalities to pass their own firearms ordinances as an addition to state gun laws.<\/p>\n We also ran linear regression models to predict fatal injury rates from the strength of each state's gun policies, after controlling for differences across states and years. Again, many gun control laws\u2014such as buyer background check and safe storage laws\u2014significantly predicted lower suicide and homicide rates. Mental health reporting laws, on the other hand, did not. These results suggest that these more traditional gun control laws work.<\/p>\n To remove linearity constraints, we focused on homicides and fit a random forest<\/a> regression model (a machine learning model that does not assume linear effects) with the gun control policy strengths for each state and year. This again identified a set of policies, which did not include mental health reporting laws, that each independently predicted lower rates of fatal injuries from homicides.<\/p>\n These findings underscore the need for the national debate on gun laws to be guided by real data, rather than convenient political maxims or easy compromises. Our findings align with existing literature in support of one clear conclusion: A set of fundamental gun control policies has consistently been strongly associated with lower rates of fatal injury, whether from suicides or homicides.<\/p>\n In the wake of the El Paso and Dayton shootings, several lawmakers joined Trump in pushing for a particular type of mental health-related gun law: \u201cred flag\u201d laws that would allow either individuals or law enforcement to petition courts to temporarily confiscate firearms from those who pose a threat to themselves or others. Senators Lindsey Graham, Chuck Grassley, and John Thune have joined the chorus,<\/a> seemingly eager to chart a politically safe course on an otherwise hot-button issue. But conspicuously missing from the conversation is proof that red flag laws will actually reduce gun violence. That\u2019s because to date there isn\u2019t any.<\/p>\n Part of the problem is these laws are so new there isn\u2019t much data available. Before 2018, only five states had implemented any form of red flag law<\/a>, limiting our ability to test for significant effects on gun violence. But given the disappointing data on mental health reporting laws, it\u2019s wrong for legislators to champion red flag laws as though they are a panacea to the growing crisis of gun violence in America.<\/p>\n The August 31 massacre of seven people in Odessa, Texas, is being cited<\/a> to push for red flag laws, but if anything, that tragedy reveals their inherent limitations in preventing gun violence. Although the shooter's mental health history prevented him from passing a federal background check<\/a>, under Texas's loose gun-purchase laws he was able to legally buy his assault-style rifle anyway through a private sale. Even if Texas had a red flag law\u2014which it doesn't\u2014we have little reason to believe the police or the shooter\u2019s family would have petitioned to take his weapons away. He reportedly lived alone, without running water and with only a dog for a companion, and when neighbors reported<\/a> that the shooter threatened them, the neighbors claimed that law enforcement couldn't find his house and gave up.<\/p>\n At best, red flag laws are a worthwhile experiment that states and municipalities should be encouraged to run. But at worst, they are a distraction from gun control policies that we already know to be effective. It\u2019s too early to say whether red flag laws work, but one thing is certain and empirically verifiable: stronger fundamental gun policies, fewer deaths. We shouldn\u2019t allow our lawmakers to ignore what works and instead tout theories about what might.<\/p>\n WIRED Opinion publishes articles by outside contributors representing a wide range of viewpoints.
