On a Monday night in late March, Calum Best, then a senior at Liberty University, received an unexpected call from an unknown number.
Best picked up his phone. The caller was Scott Lamb, a senior vice president who handles communications at the evangelical Virginia college. Lamb informed Best that he was looping in fellow senior Derek Rockey to listen. Best was confused and worried that he had messed up somehow at his on-campus job, where Rockey was his boss.
