The Supreme Court on Monday empowered police to stop people on the streets and question them, even when it is not clear they have done anything wrong.

In a 5-3 ruling, the Supreme Court relaxed the so-called exclusionary rule and upheld the use of drug evidence found on a Utah man who was stopped illegally by an officer in Salt Lake City.

The Supreme Court first adopted the exclusionary rule for federal cases in 1914, but greatly expanded its reach in 1961 by applying the rule to state and local police. The rule generally requires judges to throw out evidence if a police officer or federal agent conducted an unreasonable search, including stopping a pedestrian without reasonable suspicion that the person had committed a crime.
