They took copies of the files that they believed related to her, so any simple password or ordinary encryption would eventually have been overcome. Thanks to PGP her whereabouts and her life were protected. This incident and the young woman's circumstances are well documented. We have also had other incidents where PGP protected files and so protected innocent people. If the US confirms the dubious precedent of denying privacy in a cavalier fashion by trying to deny people PGP , it will be used as a standard by which others will then engineer the outlawing of any privacy.
Partial privacy is no privacy.
Our privacy should not be by the grace and favour of any Government. Mediums that ensured privacy in the past have been compromised by advances in technology, so it is only fair that they should be replaced by other secure methods of protecting our thoughts and ideas, as well as information. I wish you well with your hearing.
