I have been personally affected (not the arrested!) by two DUI arrests by one officer, and actually was willing to testify to his outrageous behavior, but he didn't show up in court the first five times he was supposed to, and the sixth time, the judge threw out his testimony and kicked the case, before I was able to testify.  I can only imagine how many times this has happened. I spoke to his sergeant after the first incident, who just shook his head and apologized, but informed me he was about to retire and nothing came of it.  The guy is now a detective! It is such a shame we have to protect ourselves from police officers.  It seems the police department is as corrupt as the city and state governments.
