One of the comments under the article about the Raleigh NC gun show ND gave us this little gem about what really happened:
Got the goods on what actually happened at the Raleigh show.
The would-be seller obtained the gun from his brothers estate. He wasn’t a gun guy, but thought to sell it at the show. Problem was, it was loaded, and being a non gun savvy person, never thought to check. While removing it from the case, apparently he put his finger inside the trigger guard. Bang.
Rule #1, my friends.
