"Justice Brett M. Kavanaugh.. opined that race can be considered along with other factors in forming reasonable suspicion to stop someone for an immigration check..."

"... such as where people are gathering and what jobs they are working. 'To be clear, apparent ethnicity alone cannot furnish reasonable suspicion; under this Court’s case law regarding immigration stops, however, it can be a "relevant factor" when considered along with other salient factors,’ Kavanaugh wrote. The court’s three liberal justices sharply dissented. 'We should not have to live in a country where the Government can seize anyone who looks Latino, speaks Spanish, and appears to work a low wage job,' Justice Sonia Sotomayor wrote in the dissent. 'Rather than stand idly by while our constitutional freedoms are lost, I dissent.'"
