(Reuters) - Parents agonized over whether to send their kids to school and cautious educators locked down schools at the first hint of trouble on Monday, making for a nervous first day back to school since the massacre in Connecticut.
Schools fearful of "copycats" or troublemakers who might phone in empty threats grappled with how to respond and whether to discuss Friday's shootings with children. Many revised their security protocols, wondering if there was any way to keep a rampaging gunman from breaching their walls.
