Yeah unless the goverment controlls the whole product which is pretty likely in this case since the U.S  publicly funds our beloved tor project.
I believe they have a means to store all this data and sort through it with ease but most of us are safe since we are not involved in high-level political schemes, those that do find them in the crosshairs of the agencies are not heard of in the media once disposed.

P.S it is what i believe in and am afraid of.
