College campuses across America are experiencing an epidemic of hoax calls about bogus shootings and other emergencies following the shooting death of Charlie Kirk this week.

These calls — known as swatting — panicked at least a dozen schools as police rush to campuses, chasing phantom threats with many of them being racially motivated and targeting historically Black colleges and universities.

Police say they must respond to these hoax calls about campus shootings as if they are real as the shootings become more and more common.
