I’ll bet that the business owner forgot to post a No Guns Allowed sign at the back door otherwise he wouldn’t have been robbed.
EXACTLY what I was thinking. Make sure the NO GUNS signs are big enough, not written in retartet cursive, and on both the front and the back doors. Heck, even put one on the employee uniforms. These hoodie wearing robbers simply didn’t know they weren’t suppose to bring guns in the store.
