Robbery occurred at hair salon my wife was at

At about 11:15am today, my wife was at a hair salon sitting down with curlers in her hair and about to have chemical solution applied when a white male with a beard and fleece clothing smoking a cigarette entered the salon. He started making a commotion and had his hand inside his pocket and pointing as if he had a gun. My wife ran out the door with curlers in her hair and ran next door to an insurance store and told the business owner that the salon was being robbed next door. The store owner ducked behind her desk and promptly called her husband. My wife at that point called 911 on her cellphone. The 911 asked for the address, and since she didn't know, she asked the store owner who then threw a business card at my wife while still ducking behind her desk. The 911 operator was asking a series of other questions and at the same time the store owner threw the door key at my wife and told her to lock the door while still ducked behind her desk. So my wife was talking to the 911 operator while trying to lock the door which wasn't cooperating at the same time. The store owner was yelling at her at the same time presumably to try to make my wife lock the door faster. The police showed up a few minutes later, but the robber had left with not much money since it was still morning and most likely didn't stick around because he knew my wife had run out the store. The police took statements, and my wife wasn't able to leave the scene of the crime until around 4pm. My wife said she was glad that I wasn't there because I would have done the stupid thing and try to attack the robber. She knows me all too well. I would have chanced that he really didn't have a gun since he kept his hand in his pocket, and in close quarters with multiple people to keep an eye on, there would have been an opening for me to tackle him, pin his gun hand with one hand or knee and whale on his head with my elbow. That should at least incapacitate him then, I would use my belt to hogtie him. But this is just wishful thinking at this point.
