Building web app to help expose government corruption, who should I talk to

I won't get into a long rant here but I have had enough experiences with law enforcement, the "justice" system and other aspects of government to where I am fed up and not going to take it anymore. I'm a web app developer, I've built web apps from start to finish before so I'm going to build something that I feel can help expose the things going on behind the scenes. I personally feel that there is enough info out there on the web that, if intelligentally aggregated and presented, can strike a chord with people, nothing extremist, no propaganda, just links to (or copies if legally permissable) of documents and short explanations of what they mean and why its f'ed up, so to speak, as well as perhaps links to and names of relevant people whom they should consider contacting to voice their displeasure. It would probably be best too to start with a few issues and focus around those at first rather than just a broad application about every issue under the sun.

I already have a lot of experience writing web crawlers, etc to scrape info so this part shouldn't be too hard for me, I am hoping, however to get in touch with others who share an interest and who may know more about the issues to help lead me to places that I can find document sets worth sorting through. Anyone know of any organizations, etc that I should consider getting in touch with?
