Our officers do not have body cameras, nor do we use cruiser cameras. One reason is the volume of information that would need to be maintained as a public record, and video takes up a lot of space on servers and maintaining this information is difficult in all but the largest departments.
Always assume you are on camera and being recorded. Many residents, businesses, motorists, bicyclists and pedestrians use today's modern technology to film and record everything around them.
Police officers are trained and reminded daily that anything they say or do will probably be caught on camera. The Courts here in the Commonwealth have ruled that police officers, while in the performance of their duties, do not have a right of privacy.
