Robber has balls but no gun

This robber has balls to rob a store but no real gun if asked by clerk.
Dude in Mass. tried to rob a store by claiming he had a concealed weapon. He must be hoping he may get away with some cash. But unfortunately for him, the clerk asked to show proof if he really had a gun. (Now this clerk has some) He did not had one and fled. Offcource he was arrested.
I doubt about his ability to pull trigger even if he had a real gun.
Apparently some people are not meant to commit crime.
