It is very expensive and difficult to uncover police and prosecutorial misconduct. What makes the news are only a few very rare instances where the violations were caught on camera to prove the abuse. Most all cases of abuse of rights and privileges go unnoticed. Most government civil rights agencies are not allowed to investigate or are deterred from investigating violations involving an accused person. Public defenders are not given the resources or time to investigate these violations. If those offences are not clear and in the open, they cannot challenge them.
