Utah v. Strieff, 579 U.S. 232, 136 S. Ct. 2056 (2016), was a case in which the Supreme Court of the United States limited the scope of the Fourth Amendment's exclusionary rule.
In part IV of Sotomayor's dissent, "writing only for [herself]", she wrote that "it is no secret that people of color are disproportionate victims of this type of scrutiny ... For generations, black and brown parents have given their children 'the talk'—instructing them never to run down the street; always keep your hands where they can be seen; do not even think of talking back to a stranger—all out of fear of how an officer with a gun will react to them."
Sotomayor wrote that the case "implies that you are not a citizen of a democracy but the subject of a carceral state, just waiting to be cataloged" and that unlawful stops "corrode all our civil liberties".
[13] She explained: "So long as the target is one of the many millions of people in this country with an outstanding arrest warrant, anything the officer finds in a search is fair game for use in a criminal prosecution.
The officer's incentive to violate the Constitution thus increases: From here on, he sees potential advantage in stopping individuals without reasonable suspicion—exactly the temptation the exclusionary rule is supposed to remove.
