Former soldier Jon Lewis Alexander pulls gun on liquor store robber [REAL FOOTAGE]

A would-be robber got the scare of his life after an Iraq veteran clerk pulled a gun on him during an attempted run on the cash register at a liquor store in Marionville, Missouri.

The unidentified man walked into Beer:30 smoking a cigarette. Security-camera footage shows the clerk, 54-year-old Jon Lewis Alexander, gesturing for him to leave, as smoking is not allowed inside the store. The suspect then pulled a gun on Alexander and demanded all the cash in the machine.
