What’s so funny about watching incompetent police officers? From the time of the “Keystone Kops” to the antics of the “Police Academy” movies and Leslie Nielsen’s “Police Squad,” audiences have howled at the sight of the long arm of the law unable to get out of its own way. The new ensemble comedy series “Reno 911!” (9:30 p.m., Comedy Central) joins this proud tradition of law enforcement run amok.

• “The FBI” on “National Geographic” (7 p.m., PBS) offers a far more serious approach to criminal justice. Narrated by Dennis Haysbert (“24”), this documentary presents a day-in-the-life view of agency director Robert S. Mueller.
