I think that body cameras help good police officers on the whole. There are always two sides to a story, and we send police into dangerous situations that would stress the strongest minded person over time. I agree with the idea of when in doubt trust the cop, but I know that people are not infallible. When mistakes or worse happen we all win with greater access to facts. Police officers have awesome power and massive responsibility; they deserve the resources to do the job right, our respect, and almost always our thanks.
