In 2009, the Indiana Court of Appeals likewise held that the Indiana Constitution requires reasonable suspicion to conduct a dog sniff of a private residence. See Hoop v. State, 909 N.E.2d 463 (Ind.Ct.App. 2009).
While the general public, including the police, generally have the right to approach a house’s front door (for example, to leave a flier or ask the occupant to answer a question), that license does not include an invitation to bring a dog onto the porch to search for drugs. Furthermore, although a police officer’s initial entry onto an individual’s property may be permissible, they must limit their visit to areas that can reasonably be viewed as open to them for legitimate police business and they cannot remain on a person’s property after it becomes clear to them that the purpose for their visit cannot be properly fulfilled. See, for example, Divello v. State, 782 N.E.2d 433 (Ind.Ct.App. 2003). It has been held to be unreasonable under the Indiana Constitution for police to tour a person’s property to see if anyone was home after no one responded to their knocking on the front door. Shultz v. State, 742 N.E.2d 961 (Ind.Ct.App. 2001).
But dog alerts on vehicles are not given as much protection
It is well-settled that people in their automobiles have a reduced expectation of privacy, thus a dog sniff conducted during a lawful traffic stop does not violate the Fourth Amendment or the Indiana Constitution. See Illinois v. Caballes, 543 U.S. 405, 125 S.Ct. 834 (2005); Gibson v. State, 886 N.E.2d 639 (Ind.Ct.App. 2008) (art. 1 § 11). Last month, the U.S. Supreme Court in Florida v. Harris unanimously ruled that drug sniffing dogs can provide the probable cause needed to allow a police officer to conduct a search of the vehicle, and that records of the alerting dog's field performance may sometimes be relevant but should be considered in the context of all evidence related to probable cause.
However, the dog sniff may not significantly increase the duration of traffic stops. The State has the burden to show that the time for the lawful traffic stop was not increased due to the canine sweep. See, for example, Bush v. State, 925 N.E.2d 787 (Ind.Ct.App. 2010). Furthermore, the Indiana Court of Appeals has held that police may not detain a passenger in order to get a drug-sniffing dog without reasonable suspicion. Regardless of whether police officers had reasonable suspicion to stop the motorist in the first place, if the reasonable suspicion has dissipated, further detention is illegal. See, e.g., Cannon v. State, 722 N.E.2d 881 (Ind.Ct.App. 2000).
