So what you want is the cops camera to be put at the beginning of the sift and not turned off until the end? All of this has been discussed before. If the camera is allowed to be turned off, when will it be so? Just before he talks to a confidential informant, just before he sits down with a distraught mother who a=has just lost her son to a driveby shooting, or just before the cops beats on a wise ass street punk? witnesses might be reluctant to talk to police if they knew they were being recorded. As I said most of the objections have come from the public and civil liberty advocates and not the cops or their unions.
When does it get deleted again? At the end of a shift, should there be no red flagged events? How about that event that isn't red flagged by shifts end, but come to light as important a few days later? Maybe proof that a person was in the area even though the crime happened blocks down the road and around the corner, 20 minutes later, but of sight of the cop. Ooops.The false allegation are only protected providing the camera catches it in front of the cop. It doesn't have 360 view. IIRC, Ottawa and Winnipeg tried it and dumped it for many of the reasons mentioned here, much as a result of questions raised by lawyers and legal experts, not cops.
