The law enforcement arm of the U.S. Postal Service has been quietly running a « covert operations program » that tracks and collects Americans' social media posts, including those about planned protests. The details of the surveillance effort, known as iCOP, or Internet Covert Operations Program, have not previously been made public.
I just don't think the Postal Service has the degree of sophistication that you would want if you were dealing with national security issues. ( University of Chicago law professor, Geoffrey Stone )
