"LA Confidential" is worth watching all the way through.
It's based on the book by James Ellroy, who's a pretty effective but odd writer who has a lot of interest in the LA of yesteryear. The movie "Black Dahlia" was also based in part on one of his books. If you liked the part of "LA Confidential" that you saw I imagine you'd also like "Black Dahlia".

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
