Ladies and gentlemen, Justice Kavanaugh's solo concurrence from Noem v. Vasquez Perdomo:

Immigration stops based on reasonable suspicion of illegal presence have been an important component of U. S. immigration enforcement for decades, across several presidential administrations. In this case, however, the District Court enjoined U. S. immigration officers from making investigative stops in the Los Angeles area when the stops are based on the following factors or combination of factors: (i) presence at particular locations such as bus stops, car washes, day laborer pickup sites, agricultural sites, and the like; (ii) the type of work one does; (iii) speaking Spanish or speaking English with an accent; and (iv) apparent race or ethnicity.

...

Under this Court’s precedents, not to mention common sense, those circumstances taken together can constitute at least reasonable suspicion of illegal presence in the United States. Importantly, reasonable suspicion means only that immigration officers may briefly stop the individual and inquire about immigration status. 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. Only if the person is illegally in the United States may the stop lead to further immigration proceedings.
