There is nothing at all here that suggests that this subpoena was unwarranted, a warrantless wiretap etc.
I agree -- that's what I wrote in my blog entry (http://127.0.0.1/blog/2008-02/2008-02-16.html).
A technical error at an ISP, the FBI notices and asks the ISP to stop. Destroys the rest of the data (if not all of it .. there's enough rules of evidence to make out a case that whatever was gathered has been tainted). End of story.
No, I think there's more. The lesson is that mistakes like this do happen, and proper *system* design takes that into account. That might be mundane -- have a procedure in place for dealing with unauthorized data, rather than trusting individual agents. (I have vague recollections of reading a few years ago about some Carnivore intercepts being destroyed by an agent who was very upset about overcollection.) The more important point, though, is to take this as a lesson in humility in system design. This time, a filtering error caused some emails to be delivered improperly. Next time, might a filtering error in a surveillance system lead to penetration of communications carrier networks? Before you say "that can't happen", think of the Greek cellphone scandal. This is precisely why I and others have long opposed tight integration of surveillance systems into communications networks. It's not that wiretaps are bad; it's that such mechanisms are all too easily subverted. --Steve Bellovin, http://www.cs.columbia.edu/~smb ------------------------------------------- Archives: http://www.listbox.com/member/archive/247/=now RSS Feed: http://www.listbox.com/member/archive/rss/247/ Powered by Listbox: http://www.listbox.com
