NEW: ICE is legally required to publish detention statistics every 2 weeks. But the data is complex.
That's why the interactive "ICE Detention Map" automatically scrapes & visualizes ICE's data, which shows, among other things, that 71% of detainees have no criminal record.

But we all know that's not going to happen, unless and until governments stop using platitudes and actually put an end to this travesty at once.
