The more troubling aspect of this story that no one seems to be talking about is that these cameras are being introduced because somewhere the presumption of innocence on the part of citizens is being abridged. We shouldn't have to require police to wear cameras to prove our innocence. The courts should be more stringent in their requirements for evidence in proving our guilt instead. Police testimony counts too much and too little evidence is required to have unconstitutional stop-and-frisks hold up in court.
