Connecticut school could not have prevented shooting, experts say
(REUTERS) - US school districts have spent millions of dollars on metal detectors, security cameras and elaborate emergency-response plans since the 1999 massacre at Columbine High School, but almost nothing could have prevented Friday's massacre at a Connecticut elementary school, security experts say.
A 20-year-old, heavily armed gunman opened fire on Friday morning at Sandy Hook Elementary School in Newtown, Connecticut, killing 20 children and six adults before taking his own life, police said.
"The school could not have stopped it without prior knowledge that he was coming," said Mr Bill Bond, a school safety specialist and former high school principal who had a deadly student shooting on his watch.
Unlike the shooting at Columbine in Colorado, where two students killed other 12 students and a teacher, the gunman in Newtown was not a student, but an adult from the community.
