But...according to John Lott...Has anyone in the US ever been murdered by a 50 caliber rifle? Apparently, No:
The one possible case of someone being murdered with a 50 caliber gun supposedly occurred about a decade ago. The initial story that I had seen was immediately after the crime occurred. Well, I was recently given this follow up article from jury testimony that indicates even in that one case the murder was not from the 50 caliber gun.
Even the gun-grabbers can't come up with a case...
