As reported, Chicago police responded to a call of gunfire at the Ford City Mall on Chicago’s south side. It turns out that a chair fell over, and a panicking shopper called 911 to report that someone had opened fire in the mall:
I think this goes to show that many people have an extreme and irrational fear of guns, to the point that they think they hear gunfire when it is just a chair falling over.
It is also important to note that had this person heard gunfire, calling the police would not have helped much. When a criminal goes on a killing spree, the police are at best minutes away, and cannot get there in time. Instead, armed citizens are the only people who can realistically stop the killer before they harm more victims. Unfortunately, Illinois bans concealed carry, meaning that only those willing to break the law (such as school shooters or mall shooters) are armed.
