It means the racial profiling got a rubber stamp, and “we will figure out the legality later.”
No one is saying they determined it was legal. They simply hand waved the issue in the short term.
Think of it like this. If cops started arresting people for saying “I don’t like cheese” and the cases got to the Supreme Court, and they said “nah it’s all good keep doing it until we hear arguments on it” that would be akin to what happened here.
I’m sorry, did they say “no you have to stop” or did they say “yeah you can keep going” because only one of those happened.
