Vic Mackey of The Shield -- another version of Eldon Perry?

There seems to be a lot in common -- angry, hard-core, street smart cops working for elite units walking and crossing the line, including being covered by and being manipulated by a crooked boss (Assistant Chief Gilroy in the Shield, Jack Van Meter in Dark Blue). Both characters had tormented relationships with their wives, although this is something of a cop drama clich�. And both characters were pursued relentlessly by black superiors -- Perry by Beth Williamson and Holland, Vic by Kavanaugh and Wyms, although Vic was pursued by a lot of people. And both cops carried Smith and Wesson 4506s with the somewhat uncommon hooded sights!

The Shield's story line was obviously a lot more invovled because it ran six years, but this movie is almost like the Season 1 story arc about the killing of Terry Crawley. The Shield version is a little darker (killing another cop, and if I remember right it was also tied up in the killing of a drug dealer who was a rival of a Mackey informant and kickback source), but there's a lot of similarities.
