COLUMBIA, S.C. — When FBI Director James Comey told a national gathering of law enforcement leaders that cops might be easing up for fear of being caught on camera, the conference attendees included a South Carolina sheriff whose deputy was about to star in the nation’s next viral police video.
Richland County Sheriff Leon Lott returned home to an uproar over images of a school resource officer flipping a 16-year-old girl out of her desk and dragging her across the floor of her math class Monday at a high school in Columbia. In announcing the deputy’s firing two days later, Lott called on the public to shoot more video, not less.
