It started as just another traffic stop.

In early March, Anthony Graber, a 25-year-old staff sergeant for the Maryland Air National Guard, was humming a tune while riding his two-year-old Honda motorcycle down Interstate 95, not far from his home north of Baltimore. On top of his helmet was a camera he often used to record his journeys. The camera was rolling when an unmarked gray sedan cut him off as he stopped behind several other cars along Exit 80.

From the driver’s side emerged a man in a gray pullover and jeans. The man, who was wielding a gun, repeatedly yelled at Graber, ordering him to get off his bike. Only then did Maryland State Trooper Joseph D. Uhler identify himself as “state police” and holster his weapon. Graber, who’d been observed popping a wheelie while speeding, was cited for doing 80 in a 65 mph zone. Graber accepted his ticket, which he says he deserved.

A week later, on March 10, Graber posted his video of the encounter on YouTube. What followed wasn’t a furor over the police officer’s behavior but over Graber’s use of a camera to capture the entire episode.
