Virginia had. Lot of success with limiting the number of purhases per month to cut back on strawman purchases. It made a statistical drop in gun violence. To truly combat that or mass shootings we need to address the why, not the how. And that isn't better psych car and red flag laws. Psychologists admit freely they can't distinguish between those who will harm people in mass shootings and the multitude of others with similar personalities. It has to be about asking what in our society prompts people to harm themselves or others and reducing those stressors. Again, why, not how or who.
