Policy Development Would you review your Video?

Policy Development You are about to view a camera recording of a use-of-force event. Understand that while this recording depicts visual information from the scene, the human eye and brain are highly likely to perceive some things in stressful situations differently than a camera records them, so this photographic record may not reflect how the involved officer actually perceived the event. The recording my depict things that the officer did not see or hear. The officer may have seen or heard things that were not recorded by the camera. Depending on the speed of the camera, some action elements may not have been recorded or may have happened faster than the officer could perceive or absorb them. The camera has captured a 2-dimensional image, which may be different from an officer’s 3-dimensional observations. Lighting and angles may also have contributed to different perceptions. And, of course, the camera did not view the scene with the officer’s unique experience and training. Hopefully, this recording will enhance your understanding of the incident. Keep in mind, though, that these video images are only one piece of evidence to be considered in reconstructing and evaluating the totality of the circumstances. Some elements may require further exploration and explanation before the investigation is concluded.
