I had forgotten about this great British made series until I started googling "police" and "sitcom" but I watched an entire season when CBC ran it here ages ago. Thin Blue Line stars Rowan Atkinson (obviously best known for Mr Bean and Blackaddar) as Raymond Fowler, a nerdy and somewhat uptight Police Inspector.
Fowler is dedicated to his police work to a fault, he also enjoys model kits but he's not all that into sex, much to the chagrin of his live in girlfriend Pat, who also is a police officer. It's the Ropers again from the country that first created them.
The rest of the crew on "Thin Blue Line" range from the sloppy cop, the straight laced professional female officer, the nemesis detective and the old guy on his way to retirement. It's a funny ensemble and Atkinson is so good in this kind of role that the whole thing clicks. Like all good Britcoms, there are only 14 episodes, leaving you wanting more..
