plant something on someone
1. to hide incriminating evidence on a person for later discovery and use in prosecution. (Drugs. Allegedly a police practice used to entrap drug offenders.) The cops planted crack on Richard and then arrested him for carrying it. Don't touch me! You'll plant something on me!
2. to conceal narcotics or other contraband on an unsuspecting person for the purpose of smuggling. (This person will bear the risk of discovery and arrest.) The crooks planted the stuff on a passenger, but couldn't find him when the plane landed. Someone had planted coke on me, and the airport security officer found it.
