Re: [tor-talk] HR4681 Sec 309 communication privacy legislation
This is all mute:
(i) the communication has been affirmatively determined, in whole or in
part, to constitute foreign intelligence or counterintelligence or is
necessary to understand or assess foreign intelligence or
Item I probably is intended to cover FISA warrants. Which is what the NSA
has been using to get info from companies already.
So I read this as they can keep the communications indef if it is encrypted
or they have a FISA warrant, FISA warrants are already NSA general
procedure for getting everyone's emails and call records.
