Chicago charter school network introduces high-tech visitor ID, weapons detection systems – CBS2 (Chicago)

The year before installation, the 18 Noble charter schools had reports of 17 weapons—a number that has dropped dramatically. "We don't want kids to feel like they're walking into some type of in prison or something like that—because that's not what it is at all," said Rhonda Cohen, manager of safety and security for Noble Charter Schools. "This is their school. It's their space. We're just reassuring them."
