Mayor Bloomberg has vowed to appeal the ruling, claiming that the stop and frisk practice works and makes the city safer. But as I pointed out in a recent post, while there is research suggesting NYC police have done a lot of good innovating, so far at least the research has not borne out stop and frisk as being one of them.
That is to say, there are other things police do in New York, besides stop and frisk, that have produced a larger than average crime drop than other cities. And they also do stop and frisk, which research hasn't found to help with that.
One more note for now is that we have also written, and more extensively, about NYC as the world's marijuana arrest capital. This is different from the stop and frisk practice, but stop and frisk undoubtedly fuels it.
