I watched this during the original TV broadcasts and purchased the DVD set afterwards. It's probably the best police corruption series that I've ever watched. It takes us from the early years when they started taking shortcuts to the later years when they had become full fledged criminals who thought nothing of flooding the streets with drugs or killing people. The thing I really enjoyed about the series was that it showed them as human beings. By the end of the series, their morals had become so twisted that they were going after people just like themselves and somehow justifying it to themselves. It was a great series and I still get the DVD set out yearly for a watch. I just finished watching the final episode and it's just as good as it was the first time I watched it. And the series is probably even more relevant today than it was back then. It tells us that power is a corrupter and too much power can become a great corrupter. I think we've all personally seen that to be true. I know I have in the people I've encountered throughout life. If you haven't watched it yet. Then stream it or buy the DVD/Blu-ray set. You won't regret it!
