FILE - In this Jan. 13, 2014 file photo, students pass by Seven Lakes High School after being evacuated and released from school for the day after a bomb squad was called to the school after a potentially explosive device was found. Threats against schools don’t just come written on bathroom walls these days. Spread using smart phone apps, social media and Internet phone services, anonymous reports of bombs or other threats of violence are forcing school evacuations and a response by police swat teams or other authorities to what in the vast majority of cases turns out to be a hoax.
