Sure, but at a state level lax gun laws are correlated with an overall increase in suicide, so it's not a free pass.

> Each law was associated with significantly lower firearm suicide rates and the proportion of suicides resulting from firearms. In addition, each law, except for that which required a waiting period, was associated with a lower overall suicide rate. Follow-up analyses showed a significant indirect effect on overall suicide rates through the proportion of suicides by firearms, indicating that the reduced overall suicide rate was attributable to fewer suicide attempts, fewer handguns in the home, suicide attempts using less lethal means, or a combination of these factors. States that implemented any of these laws saw a decreased suicide rate in subsequent years, whereas the only state that repealed 1 of these laws saw an increased suicide rate.

And gang violence. I think it's safe to say, gun crimes among gangs would just be replaced with something else if guns were taken out of the picture. (Which...removing guns is not possible nor realistic, so let's be realistic about the solutions..)
