Licking Valley Schools Superintendent David Hile shuddered when he saw the Facebook image of the boy with a menacing stare and a gleaming assault rifle. It was the same boy who, after threatening students, had been expelled from school for 80 days, the maximum time allowed under state law. And now, two days before the boy’s anticipated return, Hile felt powerless to stop the boy he saw as a clear threat despite all the red flags. Last week’s school shooting in Parkland, Florida, left 17 dead and questions about how a killer was able to fly under the radar with such a long history of intimidation. There were numerous citizens who called in warnings about Nikolas Cruz, he had had run-ins with police over incidents when his anger exploded, he had intimidated, bullied and threatened students at the school.
