I feel that a drug sniffing dog is not more invasive than a surveillance technology that we encounter on a regular basis. The court has passed the decision that the police do not need a search warrant to have a drug sniffing dogs that can search luggage at airport or at any traffic signal where the car has been stopped and a sniffing dog is passing. The sniffing dog is not considered searches in some of the hotel hallways or school locker or outside a passenger train’s sleeper.
