> [...] like pointing out how many mass shootings are done with guns that bypassed background checks. Can you name some? Better yet, can you point to data on how often this has happened? Off the top of my head, I can think of several instances where the guns were legally purchased and the shooter passed the background checks. I can think of a couple where they were stolen, and one where they were taken from a family member after that family member's murder. I can't think of any where the firearm(s) were acquired exclusively through private sale.
