Cities, theme parks adopt new weapons detection technology to curb gun violence

Weapons detection screening systems are becoming more and more common. These systems use touchless sensors to screen for objects that look like weapons in people’s pockets or backpacks, then they feed that information back to a computer system where security guards can view it. In Detroit, city leaders hope the technology can be used to prevent gun violence. As WDET’s Eli Newman reports, that means bringing security checkpoints to public spaces.
