As others said, I made an oversight in that the FBI also provides some
   info to the NSA. Info goes both ways. There are some restrictions on
   using domestic intercepts, and this is where the FBI comes in. Using
   businesses to do dirty work is also a way that the government
   circumvents certain controls and accountability that don't apply to
   companies. All major telecom companies have worked closely and secretly
   with government spying since their inceptions. Both need each other.
   You should also look into FBI's DITU in addition to DCSNet, Red Hook,
   and such specific technologies.

The NSA provides data to the FBI and DEA, among others. Although it was
known previously, this is part of what Snowden released with
corroborating documentation. That it hasn't gotten more attention, by
Greenwald, Snowden, et al, is one of the major credible complaints since
the releases began in June 2013.

Thanks M373, this was what I couldn't put my finger on, it's all been NSA, NSA s
o far... if the FBI has its own capacity to monitor phone, email, chats, etc., i
n addition to whatever NSA shares with them, that's a whole other data-sucking s
tructure that needs attention.
