Everything described in the anecdotes, unless I missed it, was basically someone going on Twitter, a global media platform designed to convey your postings to a mass audience, and then reading the things people wrote. Right?
I can think of a variety of things that could have been done after that which would be bad, oppressive things. But are they alleging that?
The headline here is "U.S. Marshals spied..."
Did they? Like if I post something WITH THE VISIBILITY SET TO PUBLIC VISIBLE BY EVERYONE WITH AN INTERNET CONNECTION EVEN NON-LOGGED IN PEOPLE and then someone reads it, then I can claim someone is spying on me?
