Mark Cicero writes: "The Canadian Supreme Court announced two 6-2 decisions today that severely restrict the use of police drug sniffing dogs. 'As with briefcases, purses and suitcases, backpacks are the repository of much that is personal. . . . Teenagers may have little expectation of privacy from the searching eyes and fingers of their parents, but they expect the contents of their backpacks not to be open to the random and speculative scrutiny of the police. This expectation is a reasonable one that society should support.'"
