Immigration and Customs Enforcement, or ICE, has stepped up its surveillance of thousands of immigrants in the Bay Area, utilizing new technology to do so. Mission Local reports the increased surveillance is part of the Intensive Supervision Appearance Program, enacted about 20 years ago. In the San Francisco “area of responsibility” – which covers Northern California, Hawaii, Guam and Saipan – more than 20,000 immigrants are under some kind of surveillance. Mission Local reports that some immigrants are complaining that the added surveillance devices are uncomfortable and make it difficult for some to find or keep work. Others told the website that they had been fitted to ankle or wrist monitors, despite not having a criminal record.
