FILE - In this file photo of Jan. 28, 2013, Capt. Bryn Reynolds of the Washington County Sheriff's Office takes a question from a student at the Hudson Falls Primary School in Hudson Falls, N.Y. Reynolds and other officers were present to show off their equipment and discuss safety and to practice drills with unloaded guns to prepare for armed intruders at the school. School security has come under more scrutiny in the wake of the Sandy Hook Elementary School massacre in Newtown, Conn., that killed 26 people in December.
