The New York Times has the details.
A military arm of the intelligence community buys commercially available databases containing location data from smartphone apps and searches it for Americans’ past movements without a warrant, according to an unclassified memo obtained by The New York Times.
Defense Intelligence Agency analysts have searched for the movements of Americans within a commercial database in five investigations over the past 2½ years, agency officials disclosed in a memo they wrote for Sen. Ron Wyden, D-Ore.
You can read the memo, too.
This ILLEGAL activity has been going on for roughly 30 months.
Please spare me the “well, if you’re not doing anything wrong, then you have nothing to worry about” argument. Extending this “logic,” law enforcement can walk into your home at any time and as often as they like, disrupting whatever it is you are doing at that moment.
At minimum, spying on Americans without a warrant is harassment. And it’s also a violation of our expectation of privacy.
We wouldn’t accept authoritarian governments or corporations in such countries spying on people, right? So, why do we know about it here at home, but shrug our shoulders as if it was no big deal?
A law is a law only if it is enforced.
