When detective Bryant gets rough while interrogating the suspect of the shooting he tells him to sit down. When we cut to a different angle we hear him repeat the last few words of his sentence.
In 2014, the series creators and network were sued for emotional distress by the family of a man named Andy Abarca. Abarca had been killed in a shooting, and actual photos from his autopsy were used in the opening credits montage of the show, evidently without any permission from his family. His mother and sister just happened to stumble across the show on one night in 2013 and were greeted with grisly images of their deceased relative. It was evidently allowed as autopsy photos are considered public documents. As of 2018, there have been no updates on the case.
