Sgt. Manny Vilar, president of the state Police Benevolent Association, who has been complaining that state parks and beaches are understaffed, told WCBS 880’s Sophia Hall there were only 22 officers on duty for the concert, which drew 15,000 people.

“It’s gambling with public safety that cannot continue,” he said. “Somebody’s going to die.”
