Tom Discenna, a professor of communication and president of the faculty union at Oakland University, convinced the union to buy 2,500 pucks at 94 cents apiece, the newspaper reported. Eight hundred were earmarked for union members, while 1,700 were allocated to students.
"It's just the idea of having something, a reminder that you're not powerless and you're not helpless in the classroom," Discenna told the Free Press.
Gordon said there are no studies or research on using pucks in active shooter situations, but he added that throwing anything with weight could hurt or distract the shooter and lead to disarming the attacker.
“Anything that you can throw that’s heavy and will cause damage, cause injury is the bottom line of what you’re trying to do," he said. "(A hockey puck) was just a thing that was suggested that could possibly work, especially when you have 20 or 30 people in a classroom and they all throw hockey pucks at the same time, it would be quite the distraction."
