what are they investigating? and is this a "criminal" investigation? seems like nobody has been charged they have cameras on her cell at all times so they know who came in/out and at what times
the arresting office won't be charged because it is not ILLEGAL for a cop to be "rude" to anyone he may get "written up" by his supervisor for lack of customer service/decorum but he did nothing against the law
