FYI, there is a new episode on american greed which pretty much shows how these type of operations worked. Insys basically gave the kickbacks by having the doctors give "speeches" but it turns out no speeches were given and the doctors got the checks anyways. https://www.youtube.com/watch?v=h2WBKkyFpRo
True, but it's not like if they did, the situation would be that much better. In a way for them they screwed up because the actually didn't bother playing the bribery sham all the way through like say political candidates do. For example, Hillary Clinton made $3M from speeches to large banks in just 2 years: https://theintercept.com/2016/01/08/hillary-clinton-earned-m... but they were actually organized enough to have "speechs". I remember the transcript of one was leaked, and you'd think they'd be some really deep insights and strategy laid out for the future that's worth $600k. But it was mostly "you all great, thanks for creating jobs etc etc". It is legal of course, but everyone know what it really is.
