I love all the people wanting the Sergeant demoted or reprimanded. We're all grown adults and we've all had the training. Everyone knows right from wrong and if you need your Sergeant looking over your shoulder and holding your hand then you won't make it as a Detective. She did shoddy work and she got caught. Most divisions have 8+ Detectives that handle hundreds of cases. It would take a separate team of Sergeants to review every casefile and their never ending changes.
