Hollis King and his two friends might be the unluckiest pot smokers in Kentucky.

The three men were sitting around King's apartment in Lexington, Ky., on a Thursday night in October 2005, when police officers knocked on the front door, then kicked it in. They did not have a search warrant.

The police were looking for a man who fled into an apartment building after selling cocaine to an informant. They heard a door slam in a hallway, but by the time they were able to look down it, they saw only two closed doors.

They didn't know which one the suspect had gone through, but, smelling the aroma of burnt pot, chose the apartment on the left.

Their quarry had gone into the apartment on the right. But in King's place, they found one person smoking pot and a small amount of cocaine and money, and arrested King and his friends.

King pleaded guilty to drug charges, but the Kentucky Supreme Court threw out the evidence against him and the conviction, ruling that the police did not have cause to burst into his home without a warrant.
