In a statement, Clark said although his husband was fatally injured by a nightclub security guard, "this ordinance goes beyond just nightclub or bar security."

"While standards and training are required for armed security in the city of Louisville, unarmed security is just as important - especially as it relates to bars and nightclubs, where just about anything can happen in an alcohol-driven environment," he said. "Bars that hire unarmed security to protect their patrons should be trained in areas of de-escalation tactics, crowd control, emotional regulation techniques, bomb or armed shooter threats, and more, as research shows that many bars hire security by word of mouth, physical stature or on social media."
