I read an article on the front page of the sunday Star Tribune called Secret, double life of a Walgreens druggist by James Eli Shiffer. Neil Thompson was hired as a pharmacist at Walgreens in 2005 and worked for 3 years to figure out how they scammed the government. He went back to law school and got a degree at age 45 and then he worked as an undercover investigator in the back offices of Walgreens. He and another employee developed a case where Walgreens overcharged insurance companies. It's a pending law suit, totaling $9.9  million and Thompson stands to win over $400 thousand. He said "I would have done it even if there wasn't a reward." I think this was very patriotic of him to do if he really did it for all the right reasons.
