“Masked men from ICE showed up one April morning, and it all stopped. The kids couldn’t leave their homes. Our weekly classes stopped,” said Vu, a Sid Richardson College freshman. “Week after week, I would hear word of another family who left without a word. We made [the map] a few weeks later.” The website, icemap.dev, tracks ICE-related news incidents in individual counties, as well as immigrant detention facilities with documented health and security inspection failures.

pretty much the same as the trackers. there are many and there is not one master list or source. They are not competing its that the efforts are grass roots bottom up. By its nature its not centralized and comprehensive on a single source.
