The past six months have given us a number of police excesses caught on camera. Police officers savagely beat University of Maryland student John McKenna and filed false felony assault charges against him. Video of the event set the record straight. Prosecutors dropped the charges against McKenna, and four officers have been suspended and are facing state and federal investigations.

The McKenna case showed the value of video as an honest witness. Yet Maryland police officers continue to make the claim that the state wiretapping law forbids recording in public. I discuss this issue in a new Cato video, Cops on Camera, along with attorney Clark Neily of the Institute for Justice and Cato adjunct scholar Radley Balko.

We are hosting an event next Wednesday, September 22, on the right of citizens to record on-duty police, and the prosecutor in the high-profile Maryland wiretapping case against Anthony Graber will be on the panel. Registration available here.
