whosarat.com might find you a list of agents and LE addresses, I have heard about it a few times but never decided to spend any money for membership , it really pissed the government off though so it probably isn't entirely worthless Pretty much people get busted and then give over all court documents and info on the informants / undercovers , and then they screen it to try and make sure it is legit info on informants/agents, and then they sell it for a membership fee. If you end up getting a membership you should try and copy the entire site and post an open source copy .
