Someone calls a bomb threat to 911, prompting the evacuation of a local TV station as police race to the scene. It is a hoax. Someone sees a package they think is a bomb, temporarily shuttering a local city hall over terrorism fears. It’s a fake. Yet another “suspicious package” is found, this time an abandoned backpack. The Los Angeles Times says the Boston Marathon bombings have left police stretched thin as they are forced to deal with troubling consequences: a surge in bomb squad calls from people who think they’ve spotted an explosive and an uptick in fake threats from people seeking attention during a time of fear and frayed nerves. “We’re getting three- of fourfold the number of bomb squad calls we usually do,” said Jim Amormino of the Orange County Sheriff’s Department. The L.A. County Sheriff’s Department has seen a similar increase. The Los Angeles Police Department said that since last week’s deadly attack in Boston, their bomb squad has been getting five to seven calls a day, a significant increase.
