Once upon a time there was an Independent Counsel appointed to look into a really boring real estate deal. Participants in this deal--passionate, smart policy makers--people we were supposed to trust, did things in stupid or sloppy manners (or egregiously abused powers, although no charges were filed), and billing records disappeared for 2 years then magically reappeared right in the middle of everything.
And none of this mattered much because while all of this was going on, someone found out that someone had a blue dress with some semen on it and all of a sudden there was a new shiny thing to focus on. Which is how Bill Clinton came to be impeached.
So if an investigation into an unrelated sex scandal happens to uncover information that trips up the very same passionate, smart policy makers who didn't seem to learn not to be stupid or sloppy 20+ years ago, well... oops.
Or "whatever you do, don't forget about Chinatown, Jake." Or something like that. I never really liked that movie (Dr. Zhivago, for those of you too young to know).
