The series was originally titled "Metro" which was the division where the show was originally going to be set. Then, the title was changed to "RHD/LA" which was used for the fall schedule announcement. CBS ordered the final title believing that people would be confused about what "RHD" stood for.

Dennis Farina was once considered for the role of Lieutenant Sam Cole.

Many seasoned technical advisors worked on the show: Chic Daniel, an LAPD living legend who served +20 years in Metro Division (C-Platoon and SWAT) ; Robert Deamer, a gang enforcement expert who is one of the most decorated veteran of Special Enforcement Unit (ex-C.R.A.S.H.); and Officer Todd Rheingold, a highly skilled Special Weapons And Tactics operator.
