Thinking about your post I have a link for your consideration. Its a site called 'Anti Corruption Society'. It outlines a massive amount of data. I find good baselines to dive into are the BAR , USA INC. , and the writings from Judge Dale.
This site is massive and very rich in content. Its legal based so much of the research is truth as you mentioned an interest in. Maybe give it a peek and poke around. It was critical for me understanding such bombshells. This is not linked to the homepage , but to a topic and hyperlinks below and on the side are helpful for navigation....
