Arguably, they shouldn't have disclosed anything at all because it may be what gave Nick and the prosecutor colluding with each other the opportunity to sweep it, but that would be my main problem with it. It doesn't appear this was some sneaky attempt to be "in the know," it was something they knew was coming out soon anyway.
Still, it's a point to consider. Perhaps if some entirely legal information exfiltration is going on, just DON'T SAY SHIT ABOUT IT until it's a fait accompli. This flurry of legal activity could have been entirely a response to stuff that was swirling around on social media.
