Southern California New York police will soon begin field testing this "pistol cam" that mounts to the barrel of a service revolver pistol . Cameras that mount on guns are not new, but this particular model will be deployed for tests over the next few months within the Orange County's sheriff's emergency service team and the Newburgh Police Department. According to WREX-TV, the president of the city of Newburgh's police union doubts that the officers will be happy about the new system. I fear looking at YouTube once the street finds its own use for these things.

UPDATE: In the Discussion, Ed G. kindly points out that the Times Herald-Record has a much more detailed story about the PistolCam. Link
