&gt; if you have a fact-based concern, we may be able to address it.<p>I didn&#x27;t quite enjoy this dismissive tone, so I&#x27;ll be more pedantic than usual. The study you cited is interesting but it&#x27;s not the end all of gun control discussion. It&#x27;s barely even the beginning.<p>First, it considers Brady scores at a state level to try to find correlation. Gun control legislation might be at a state-level but that&#x27;s a nonsensical level of granularity. My concerns are about my neighborhoods, poverty, and guns. Not the state of California as a whole with over 35 million people.<p>Second, from the article you cited:<p>&gt; Perhaps even controlling for those factors, there will be other missing factors that are hard to control for — for instance, maybe as the crime rate increases, calls for gun controls increase, so high crime causes more gun restrictions, or maybe calls for more freedom to defend oneself increase, so high crime causes fewer gun restrictions (e.g., liberalized concealed-carry licensing rules). And of course when small changes in the model yield substantial changes in results (e.g., if you calculate the state gun scores differently, the results will likely be different), you know how little you should credit the output. Figuring out the actual effect of government actions, whether gun laws, changed policing rules, drug laws, or anything else, is devilishly difficult.<p>is a succinct summary of why this comparison study is meaningless. It&#x27;s a good retort to someone who says that gun control leads to fewer deaths but it has so many caveats and such imprecise applicability that the only useful take away point is that at a state-level with some gun-control scoring pattern (viz. the Brady Campaign scores) discounting ALL other factors, gun-related deaths are not correlated to gun control.
