"ICE has built a comprehensive surveillance infrastructure that can track almost anyone at any time," said study co-author Nina Kessler, a policy associate at Georgetown University's Center for Privacy and Technology Law. The agency has strengthened its ability to monitor with near-total secrecy and impunity, circumvent restrictions and operate under the noses of lawmakers."
Just as U.S. intelligence agencies can claim "incidental" access to the data of ordinary U.S. citizens in mass surveillance of phone and Internet use in and out of the country, ICE has taken advantage of weaknesses in federal and state privacy laws, which are completely powerless to stop it, to steal from three major sources, according to the report.
