This claim, unfortunately, is true. Looking a the cited article from the claim, Brookings found 16% of Latino respondents avoided calling the police out of fear of being detained. Brookings is a legit non-profit research organization that prides itself on being non-partisan. This means the linked source from the claim is likely aiming to be as non-biased as possible. I also looked into recent events of racial profiling and came across an article from the American Immigration Council about a Supreme Court ruling in LA. The article cited the Noem v. Vasquez ruling, which overruled a previous ruling that prohibited immigration officers from detaining suspected illegal immigrants based on race or ethnicity. I was able to find the ruling report from both the concurring and dissenting perspectives. In the concurring report by Justice Brett Kavanaugh, he wrote, "The Immigration and Nationality Act authorizes immigration officers to 'interrogate any alien or person believed to be an alien as to his right to be or to remain in the United States.'" He later cited the 4th Amendment as a reason for these stops. The dissenting report also states that it was the "Government's application" for this appeal, meaning the US government called for the appeal and not any real legal processes. According to the article from the American Immigration Council, this ruling essentially gives ICE agents the "green light" to detain suspected illegal immigrants, and does not prohibit racial profiling. The concurring report also called ethnicity a "relevant factor" for detaining suspected illegal immigrants.
The dissenting opinion of the ruling called out the hypocrisy of the Noem v. Vasquez ruling, citing the earlier ruling, which prohibited racial profiling in detaining suspected illegal immigrants. Justice Sonia Sotomayor wrote in her dissenting report:
"..a majority of this Court decides to take the once-extraordinary step of staying the District Court’s order. That decision is yet another grave misuse of our emergency docket. 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. Rather than stand idly by while our constitutional freedoms are lost, I dissent."
As another commentator pointed out, the ruling not only allows racial profiling but also seems to encourage it. Justice Kavanaugh's ruling also seems to be biased, as he also claimed in his report that many illegal immigrants were coming into the country to cause harm. It seems policymakers are including their own prejudices in their endorsement of racial profiling by immigration officers.
