High-tech security installed in Detroit schools

From The Detroit Free Press: When high school students return next week to Detroit public schools, they'll pass through high-tech detection machines akin to airport security systems that snap a photo and indicate the location of any metal objects on their bodies. The systems are used in some high schools across the country, but Detroit is the first district in the nation to install it in all of its high schools, according to the manufacturer. The $534,000 security system is one of several new features the school system is rolling out this fall in an effort to increase safety.
