Bordertown: Laredo

While each episode builds dramatic tension as initial tips and drug dealing arrests inevitably lead to the promise of taking down a major cartel shipment, the personalities of the members of the narcotics team prove just as engaging.

The series somehow still lacks tension as the narcs go from one bust to the next interrogating perps who all say the same thing: "I don't know anything."

It's unglamorous, nuts-and-bolts police work, applicable to a wide range of law enforcement situations, and that's where much of the show's interest lies.
