It would be a more certain bet that they’ve done this with the AT&T surveillance than putting money in any cryptocurrency.
Even knowing that parallel construction exists, it's still pretty shocking to see it used in practice.
eg I'm aware of a case here in Seattle where the Seattle PD coordinated with the feds to use a Stingray in the arrest of a fugitive. They thought they knew exactly where he was, and just used the Stingray to confirm his location before using a cooperating informant to lure him out of the building.
The police report of the incident has all of the officers creatively neglecting to write the full truth of how the arrest occurred, not a peep about the Stingray at all.

Really, the best reason (from the security org point of view) not to collect so much surveillance on your home population, is because it creates a single point of failure for foreign adversaries to gain access. Most of the interesting data is already commercially available for advertising.
"The Houston HIDTA officials told my staff that all Hemisphere requests are sent to a single AT&T analyst located in Atlanta, Georgia, and that any law enforcement officer working for one of the federal, state, local and Tribal law enforcement agencies in the U.S. can contact the AT&T Hemisphere analyst directly to request they run a query, with varying authorization requirements. The Houston HIDTA officials confirmed that Federal and state law enforcement agencies can request a Hemisphere search with a subpoena, which is a directive that many law enforcement agencies can issue themselves (except in California and Texas, where a court order is required by state law). They also explained that Hemisphere searches are not required to be in support of drug-related investigations."
Just one poor sap with an ODBC to a DB2 database and a panache for Excel stands between law enforcement and state mass surveillance...
Why would they be?
If I had such a system, why would I waist it chasing pot dealers?
To complain about the system on that basis not only makes no sense at all, but totally misses the point of being against mass surveillance. It makes me wonder if these people are actually against mass surveillance at all?
