"The Shield" is a brilliant action-packed police drama focused around bad cops set in L.A. Thankfully doesn't do the cliche "bad cops are scum" thing. The writers manage to write storylines that at times have you really sympathizing with the bad cops by showing some of their good human nature too.

It also showed the internal politics among the police hierarchy. The main characters normally are usually walking the gray line or crossing right over it.

Brilliant, fast-paced story lines with lots of hooks and twists to keep you riveted. It ran for 7 seasons and finished with an amazing ending. I highly recommend it.
