IMO, ralph Lamb played a major role in the downfall of mob rule in LV.

I didnt know that he was actually portraying a real person. How is it possible that the real Ralph Lamb was never killed? I am guessing he was on the take?

Are there any documentaries or movies that tell the story of vegas that is pretty close to fact?

Here is an article that I just read after reading your post.
