Is sniffing at the front door of a private home by a trained narcotics detection dog a Fourth Amendment search requiring probable cause? Is a "drug dog" somehow like a manmade technology, such as a thermal imaging device? These were a couple of the questions recently presented to the U.S. Supreme Court during arguments in "Florida v. Jardines." The case provides an engaging kickstarter for classroom discussion about current issues related to the Fourth Amendment. A teaching activity included in this article will provide students with an opportunity to learn about historic Supreme Court decisions around some important Fourth Amendment issues, and equip them with information to discuss the possibilities in "Florida v. Jardines." (Contains 3 notes.)
