Brief filed: 09/04/2012


Florida v. Harris

United States Supreme Court; Case No. 11-817

Prior Decision

Decision below 71 So.3d 756 (Fla. 2011).


An alert by a “trained” or “certified” drug detection dog by itself is insufficient to establish probable cause; evidence of a dog’s reliability is but one factor in a totality-of-the-circumstances analysis recommended by the Florida Supreme Court. Real-world data demonstrate that even trained or certified dogs have a high rate of false alerts; brief lists a number of different factors relating to a drug dog’s reliability.
