When the Supreme Court weighed in on Noem v. Vasquez Perdomo last month, the Republican-appointed justices cleared the way for federal immigration officials to use racial profiling. A concurring opinion from Justice Brett Kavanaugh proved to be especially important.
As the Trump appointee concluded, ICE agents can legally detain someone if they have a “reasonable suspicion” that the person might be undocumented. Kavanaugh envisioned a real-world model that was efficient and effective.
“[R]easonable suspicion means only that immigration officers may briefly stop the individual and inquire about immigration status,” the justice wrote. “If the person is a U.S. citizen or otherwise lawfully in the United States, that individual will be free to go after the brief encounter. … If the officers learn that the individual they stopped is a U.S. citizen or otherwise lawfully in the United States, they promptly let the individual go.”
In legal circles, this quickly became known as “Kavanaugh stops.”
At first blush, some might see the process the justice described as reasonable: ICE agents stop suspects; the suspects prove they’re here legally; and the suspects then go about their day. What’s so bad about a “brief encounter”?
In practice, quite a bit.
The New York Times recently reported, for example, that “many” U.S. citizens have been taken into custody. “While many of those detained have immediately declared their U.S. citizenship to officers, they have routinely been ignored. … In some cases they have been handcuffed, kept in holding cells and immigration facilities overnight, and in at least two cases held without access to a lawyer or even a phone call.”
But how many is “many”? ProPublica tried to document the scope of the problem:
