Stop and frisk has been around for decades, but recorded stops increased dramatically under Bloomberg's administration to an all-time high in 2011 of 684,330, mostly of black and Hispanic men. Four minority men who said they were targeted because of their races filed a lawsuit, and it became a class-action case.
To make a stop, police must have reasonable suspicion that a crime is about to occur or has occurred, a standard lower than the probable cause needed to justify an arrest. Only about 10 percent of the stops result in arrests or summonses, and weapons are found about 2 percent of the time.
Scheindlin heard a bench trial that ended in the spring and coincided with a groundswell of backlash against the stop-and-frisk tactic. She noted in her ruling this summer that she wasn't putting an end to the practice, which is constitutional, but was reforming the way the NYPD implemented its stops.
The Center for Constitutional Rights, which represented the four men who sued, said it was dismayed that the appeals court delayed "the long-overdue process to remedy the NYPD's" stop-and-frisk practices and was shocked that it "cast aspersions" on the judge's professional conduct and reassigned the case.
