>What should happen if a police officer steps outside of their legally-restrained role which unfortunately exists in a fast-paced, high-tension environment with a lot of grey areas and "he said, she said."

What SHOULD happen is that even the slightest possible hint of impropriety is met immediately with strict discipline, because any organization that has a state-sanctioned right to use force against human beings has to be held to the highest possible standard.

Police officers should have it drilled into their heads that every action is held to scrutiny and judged, and should be constantly reminded that they serve the public and not the other way around.
