"From a prosecutor's standpoint, they have to prove a case beyond a reasonable doubt, and so a classic cooperator who is trying to curry favor is not always a credible witness," said William Gould, a former assistant U.S. attorney who worked in both the District and the Western District of Virginia. "If you get a couple people like that, what you might do is an operation with a law-enforcement officer, like an FBI agent. It really locks down a case in a way that just a cooperator couldn't just explain."
"The public feels that athletes are having a nice time. They'd like to be able to play these games and get compensation for them," Gould said.
