I saw this map in a different magazine last night. While it's great, it should be mentioned that the map has a notation at the bottom saying it's a copy of a map hosted off-site and may be out of date. "Click here to go to the original hosting site", or similar words.
And the site that it links to is ICE.
So, thoughts: It's great that this is being mirrored off-site, but the mirror may be outdated. ICE may also contaminate the original data at some point. And if you want to access the actual current map, ICE will have your IP address (and has an executive order saying they can raid your house without a warrant), so perhaps take some precautions before clicking on that link.
