Does New York's "stop and frisk" policy violate unreasonable search?

A higher court ruling has over turned a recent judgment banning the NY police policy of randomly stopping and frisking people. On the face of it, this policy seems to me to be an egregious violation of the fourth amendment's prohibition of unreasonable search and seizure. However, living at the opposite end of the country, in southern California, I haven't been following the details of this story, nor am I knowledgable about the details and special issues with respect to New York City. I'm interested in what others in this forum think about this issue.
