For people who work at downtown bars and nightclubs, a special training Tuesday night showed them how to respond to and prevent active shooters.
Robert C. Smith is a former police officer who now travels the country trying to teach bar and nightclub employees how to protect themselves from shootings.
"The most common active shooter will buy a table in the VIP section, maybe here on the dance floor," Smith said. "But then they get bumped. Their shoe gets stepped on. They get angry. They pull out their gun and start shooting."
