(Update 1/19/14 9pm: Hoboken Mayor Dawn Zimmer now claims that she met with federal prosecutors for several hours earlier today to discuss her rather explosive allegations that Christie Administration officials pressured her to support a real estate development as a quid pro quo for state funding in the aftermath of Hurricane Sandy flooding damage.)
Now that it is likely that there are multiple criminal inquiries into Christie Administration and/or the Port Authority of New York and New Jersey, with the precise subject matter yet to be revealed, it is uncertain where many people working in any of those orbits will fall in terms of any provable role in any wrongdoing.
And remember one thing: You don't need to have done anything wrong to be "involved" in an investigation. In fact, your factual innocence may put you at greater risk. The reason is simple: You are within the orbit of people who have done something wrong, and who may need to blame others in order to build a case for leniency from prosecutors whose support is crucial in convincing a sentencing judge to go easy on any sentence for the crimes to which they admit. Therefore, being innocent is no protection, none at all, from a false yet plausible accusation made by someone desperate to reduce or avoid all jail time. And prosecutors get fooled more than you might think (but won't admit it) by con artists who have been manipulating people all their lives.
