Commentary: Gun-Rights Advocates Say Places That Ban Guns Attract Mass Shooters. The Data Says They’re Wrong.
Debunking the myths about gun-free zones

..... When a “good guy with a gun” does intervene in an active shooting, things can go terribly awry. On June 8, 2014, an armed couple burst into a CiCi’s Pizza in Las Vegas screaming, “This is the start of a revolution!” They quickly gunned down two police officers eating lunch, and then moved to a nearby Wal-Mart. One customer, a concealed-carry license holder, drew his gun rather than flee, but was immediately shot. As it would turn out, all three of the couple’s victims that day were armed.
Another example: On Jan. 8, 2011, a gunman opened fire on an outdoor meeting between Rep. Gabrielle Giffords and her constituents in Tucson, Ariz., killing six and wounding 13. When the killer was forced to reload, he was tackled by a bystander. Having heard the gunshots, an armed man ran to the scene. He saw two men wrestling and assumed the wrong man was the shooter. Had it not been for other bystanders quickly correcting him, he could have ended up shooting the wrong person. Afterwards he stated: “I was very lucky.”
