… a source familiar with the matter told NBC News that James Trump, a senior litigation counsel in the U.S. attorney’s office in Alexandria, Va., sent an email to Levison’s lawyer last Thursday – the day Lavabit was shuttered — stating that Levison may have “violated the court order,” a statement that was interpreted as a possible threat to charge Levison with contempt of court.

That same article suggests that the decision to shut down Lavabit was over something much bigger than just looking at one individual’s information — since it appears that Lavabit has cooperated in the past on such cases. Instead, the suggestion now is that the government was seeking a tap on all accounts:

Levison stressed that he has complied with “upwards of two dozen court orders” for information in the past that were targeted at “specific users” and that “I never had a problem with that.” But without disclosing details, he suggested that the order he received more recently was markedly different, requiring him to cooperate in broadly based surveillance that would scoop up information about all the users of his service. He likened the demands to a requirement to install a tap on his telephone.

It sounds like the feds were asking for a full on backdoor on the system, not unlike some previous reports of ISPs who have received surprise visits from the NSA.
