"Guns don't kill people, bullets do" or so the saying goes, but 59-year-old Verlin Q. Alsept was a bit unclear of the concept that you still need that gun:

Rather the fellow who entered a Family Dollar Store in Dayton on Tuesday threatened the cashier with a bullet — a single .38 caliber round he pulled from his pocket.

The 59-year-old man asked the cashier for all the money in the cash register. Unfazed by the threatening bullet, she declined, and he left the store empty-handed. A nearby private security guard at the Westown Shopping Center — alerted by the cashier — quickly ran the man to ground as bystanders called police.
