A man wielding two handguns was shot and killed at a Walmart in Pennsylvania, authorities said.The man walked into the store in Stroudsburg late Saturday night and started pointing a gun at people, Pennsylvania State Police said.Stroud Area Regional Police were called to the scene. Officers arrived and told the man to drop his gun, but he refused and pointed his weapon at police, authorities said.Officers shot the man in the upper chest area. He was pronounced dead at a local hospital.
And he hadn't yet used it, either.
Lessons to be learned.
