Terry stops are. The complaint that they made in New York was that the stop and frisk searches were racially motivated and done without any reasonable suspicion of past or impending wrong-doing on the part of the person being frisked. Any future challenge would certainly use that argument.
Such hypocrisy.
It would seem to me that police officers should at least be required to log stop and frisk searches, including the subject’s identity, time and date, and some explanation for the stop beyond “suspect looked suspicious”. (Maybe this is already required?)
Do roadblocks that stop everyone on a road, for DUI, meet the “reasonable suspicion” test?
