“Dirtbox”
The Military engages in C.E.W. and arial Surveillance; (Of course, in normal circumstances they are prohibited from surveilling U.S. Citizens. Have we left “Normal” yet?)
The FBI and CIA (Die amerikanishe Geheime Staatspolizei) use “Dirtboxes” under, I am sure, some perfectly legal broad general warrant issued by a minor magistrate judge in DC. (Sarc off/)
