At the Frontline: Former N.Y. Homeland Security Advisor Michael Balboni

Terrorism expert weighs in school security strategies in wake of Newtown tragedy

Balboni: It’s that, and layered response. Perimeter security, internal security, locked doors, entryways, cameras, response capability both internally and externally with the police, it’s all part of the awareness and cooperation that you need to have. Security is not a destination, it’s a journey. There’s no such thing as being completely safe.
