Last Friday, a day after a gunman killed nine people on an Oregon college campus, Cobb County school police got a tip that a middle school student had threatened to “shoot up” a school.
Officers went to the student’s home. The student denied he made a threat. No weapons were found. No charges were filed.

In today’s world, where school shootings are not uncommon, you have to take threats seriously, explained Ron Storey, the school district’s chief of police.
