That requires having a degree of certainty supporting any attempt to name names. If you're not certain they lied to you, then your new story is potentially libel. For example, let's say they were given information they were certain was correct, and they handed it to a journalist in confidence. They're a trusted source. You both got duped. What's the value in burning them publicly, especially if you're going to do it by calling them a liar and exposing yourself to risk? There are cases where the press really needs to take people to task but the amount of secrecy and ambiguity in this story makes it seem like a case where it can't (or shouldn't) be done.
