A pool of govt #data is especially powerful when combined w/private-sector data, such as… #mobile-#phone #geolocation data…could make inferences about actions, activities, or associates of…anybody perceived as a govt critic or #dissident.…The govt’s current use of combined data in service of #deportations—& its refusal to offer credible evidence of wrongdoing for some of those deported—suggests the admin is willing to use the data for #political aims.
