Valentino co-founded the Early Warning Project, which assesses the risk of mass atrocities around the world. To be sure, anti-immigrant violence in the United States does not approach the scale of the atrocities Valentino usually studies. But the dehumanizing language of the sort used by the Trump administration is, he said, “a pretty standard indicator” of risk, a necessary if insufficient condition of mass violence directed at a particular group.
“It’s not that it turns normal people into murderers,” Valentino said. “It’s that it turns them into bystanders.”
To the extent that the Trump administration has pulled back on its violent anti-immigrant campaign, it has done so because nonimmigrants have stepped up — in the courts and, especially, in the streets. The most dramatic confrontations took place this past winter in Minneapolis, but in the months since the federal government ended its occupation of that city, resistance has continued. In Newark, N.J., demonstrators have been protesting the conditions at the Delaney Hall ICE detention facility. At least 63 people have been arrested in the past week alone. In New York City, a relatively new coalition called Hands Off NYC has, since January, trained more than 7,000 volunteers to peacefully resist ICE. The Aliens web page, Valentino thinks, is intended to discourage this kind of activity.
“The key is that you are supposed to see your city with a big red dot over it,” Valentino said, referring to a map on the website, then click to read, supposedly, the number of immigrants who have been charged with crimes. (For example, “Jamestown, N.Y.: 10; Larceny, Obstructing the Police; Ecuador, Guatemala, Mexico, Nigeria.”) “And you see the charges — do you want to risk your life for this kind of person?”
When the page went up, the American Immigration Council, a pro-immigration advocacy organization, happened to be hosting a gathering of data experts. Participants thought they saw something interesting. “The page is poorly coded, badly designed, and yet weirdly transparent about some things the administration hasn’t been transparent about before,” Aaron Reichlin-Melnick, a senior fellow at the council, told me. It appeared that the map was based on raw data of ICE arrests — information that the government had mostly kept secret since the beginning of President Trump’s current term. The map is possibly the best document to date of the scale of the ICE campaign, which, it shows, has raged not only in big cities but in small towns, where it’s sometimes less visible.
