I don't always assume that. But when an officer here in IN gets caught on tape saying "Is that recording, I know how to delete it, do you want me to delete it for you" when referring to another officer's body cam. It does make you wonder a bit.
I'll have to disagree. It can tell an accurate story, what the officer did or didn't see is a different story.
They rarely, very rarely tell the whole story or anywhere near it. If an officer wearing a body cam is facing north the camera is recording what is north of the officer. If the officer turns his head to the east the officer sees what is east of him and the camera is still recording what is north.
Cameras have infinite focus, human eyes don't.
Cameras see much better in low light than human eyes do.
Humans can compensate and maintain focus on an object while in motion, cameras don't.
All of these create significant issues when you consider that people will put 100% more faith in what they can see for themselves than what an officer says they saw. We also now have groups which three years ago were screaming for every officer in the country to wear a body camera, now don't want officers wearing them. They also don't want officers to be able to watch the video themselves before writing a report yet they want to be able to use the video to judge the officer's actions.
I wish the technology existed which could show exactly what the officer sees, when it happens I believe every officer in the country should wear one but until then I'm 100% against them.
