“Incompetent” is a polite way to describe the Reno County Sheriff’s Department as depicted on Comedy Central’s Reno 911! Catching criminals seems to be more about luck than skill, though most of Reno’s crime is pretty minor. Big cases tend to be taken away from the deputies, usually with good reason. But in the big-screen adaptation of the show, the deputies find themselves in charge of policing Miami when a biological-weapons attack traps the nation’s police departments in a convention center. Although the deputies spend a good deal of time partying and trying to pick up members of the opposite sex, they also manage to find the perpetrator of the attack, snag the antidote to the bio weapon, and break up a drug ring. Luck plays a role, but they also show some surprising competence, as when Lt. Garcia (Carlos Alazraqui) pilots a military helicopter to save the day. Well, one of the other deputies accidentally fires a missile and kills the suspect, but that was probably inevitable.
