The detectors have been used at three events so far – the Grand Prix, Movement, and Motor City Pride. Hayes said they have stopped people from bringing weapons into the events.
Hayes said if someone is
legally carrying a weapon when they
try to enter an event, such as the Ford Fireworks, later this month, they will be
recommended to secure it.
"If we do find that someone is unlawfully carrying we will constitutionally take the next steps," he said. "If we can get one weapon out of the wrong hands, it’s a win."
