You are mistaken, staff are required to be in TS but they don't specifically have to be in the staff channel, you can refer to the staff handbook under general expectations while on duty "4). When on the Server you are expected to be in TeamSpeak." It does not state they must be in the staff section.
Prada stated he got into the car and pressed his carjack bind "g" but for some reason it wasn't binded, regardless of it not being binded or not he got in the car with the intent to steal and didn't advert car jack which you are meant to advert before getting into said vehicle making the failrp warn valid specially if you got into a active situation right after.
The whole state trooper shooting you is a state trooper report to his command and or your own staff sit for it.
