CHARLOTTE, N.C. – Quinten Canty barely remembers a time before school shootings-and school lockdowns-were the norm. “They’ll go over the intercom and they’ll say, ‘lockdown, lockdown, lockdown’,” Canty said. “What we’re supposed to do is we’re supposed to hide in the safest corner where no windows are or farthest away from the door. Some teachers encourage that we have people like holding desks and chairs.”
