text: Most police will only use force if necessary, but a few are rotten and should not have a badge or gun. Almost always given the benefit of the doubt in the past, cell phone cameras have dramatically created questions about some police conduct. Unarmed citizens should not expect to be be shot and killed when pulled over for a broken tail light. The way I see it, cameras will protect police officers from false accusations far more often than not, but police that misuse their power and authority need to be purged and prosecuted. Police need to be trusted by the public, not feared. The BLM movement has some legitimate issues as nearly any black person can tell you.
