As School Threats Proliferate, More Than 700 Students Are Arrested

Earlier this month, a detective knocked on Shavon Harvey’s door, in suburban Ohio, to ask about her son. The son had sent a Snapchat message from her phone to his friends, saying there would be shootings at several schools nearby.

She rushed to the police station, where her son was already in custody, but the police did not release him. He was charged with inducing panic, a second-degree felony, and officials kept him in detention for 10 nights.

He is 10.
