The series makes law enforcement look like a joke, which is great for the sake of comedy but isn't meant to be serious message.
Since this is a show about law enforcement, guns are a regular part of the action. But all violent acts are committed in the name of comedy.
Officers regularly encounter prostitutes, strippers, and cross-dressers as part of their daily beats. Nudity (of the breasts and buttocks variety) is sometimes implied but always blurred out.
Minor swearing ("pissed," "damn," "whore," "bitch," etc.) is frequent, but usually used for comic effect. More serious infractions ("s--t," "f--k," "motherf----r") are also frequent but are bleeped out.
In Reno, "the biggest little city in the world," gambling is a visible cash cow.
Drinking, Drugs & Smoking
Drug busts involving cocaine, crack, and marijuana pop up on the police scanner from time to time. Cops are also occassionally called in to break up drunken brawls -- and sometimes take part in them, too.
