It was called organized crime syndicates, and it had lists of every criminal organization in every country. I only went on there for mob stuff though. It had every family and all the bosses, under-bosses, consiglierie, captains, soldiers, and associates. On some families, like the Kansas City family, what they were before they became a organized family. This was the most credible site to me, but it disapeared. There was another mob site called Murder, Inc that showed the families and what not. If any one knows where the site relocated to or wherever it went please drop it in this post.

Here are some I found on my own
