January 11, 1996, public e-mail message from Phil Zimmermann:
My lead defense lawyer, Phil Dubois, received a fax this morning from the Assistant US Attorney in Northern District of California, William Keane. The letter informed us that I "will not be prosecuted in connection with the posting to USENET in June 1991 of the encryption program Pretty Good Privacy. The investigation is closed."
This brings to a close a criminal investigation that has spanned the last three years. I'd like to thank all the people who helped us in this case, especially all the donors to my legal defense fund. Apparently, the money was well-spent. And I'd like to thank my very capable defense team: Phil Dubois, Ken Bass, Eben Moglen, Curt Karnow, Tom Nolan, and Bob Corn-Revere. Most of the time they spent on the case was pro-bono. I'd also like to thank Joe Burton, counsel for the co-defendant.
There are many others I can thank, but I don't have the presence of mind to list them all here at this moment. The medium of email cannot express how I feel about this turn of events.
