The Matching of the Bullets to the Gun

The murder weapon is the bullet. It's the bullet that kills the victim. So did they compare the bullets to Jennings revolver? They were able to do that in 1910 because they omitted it and his attorneys leaned so heavily on the fingerprint. I'm assuming they didn't find the bullets or I don't know if it was a through and through and went out the door. There are times, you know, with gunshots, bullets sometimes fly into what we call never neverland.
