20. Don't think they addressed exigency, but the SC's recent decision allows racial profiling during immigration raids.

'How the Supreme Court’s Latest Decision Clears the Way for Racial Profiling During Immigration Raids'

"This week the U.S. Supreme Court issued a decision that clears the way for racial profiling during immigration raids and sweeps."

"Now we could see the Trump administration rapidly expand the racially discriminatory ICE practices we have already seen terrorize families, workplaces, and communities around the country for months—and thanks to the Supreme Court, these raids are more likely to sweep in US citizens and people with lawful status."

"In a 6-3 vote in the case known as Vasquez Perdomo v. Noem, the Supreme Court granted an emergency request from the Trump administration and temporarily halted a LA judge’s order that barred 'roving patrols' from snatching people off California streets and questioning them based on how they look, what language they speak, what work they do, or even where they happen to be. Both a Los Angeles federal court and the 9th Circuit Court of Appeals had ruled that these actions amounted to illegal racial profiling."

"On Monday, the Supreme Court issued a brief, unsigned order that overturns those decisions. This gives immigration agents a 'green light' to once again stop anyone they guess to be here illegally—even if a central reason for the stop was race. This endorses ICE and Border Patrol targeting any Latinos they observe in Los Angeles speaking Spanish or working in low-income jobs, and then demanding their papers."

Vasquez Perdomo v. Noem was about allowing racial/ethnic profiling to stop and question suspects. What happened in that Chicago apartment building was a clear violation of Fourth Amendment rights.
