Geoffrey Thorne's character is listed in the credits as Wilson Sweet, but his name badge says Willson Sweet.
In the opening credit sequence, the scene behind Alan Autry is reversed.
In the final season, all of the major long time characters are now senior police officers holding the ranks of Sergeant through Captain. In most every police department, these are "desk jobs" which hardly ever leave the police station, yet in order to keep the action with the main characters, the show has these senior police officials performing routine tasks such as street patrol and first responding to crimes.
