The New American: Do Tech-sniffing K9s Violate the Fourth Amendment? by Joe Wolverton, II:
For several years, police and the FBI have been secretly training dogs to sniff out thumb drives, SD cards, and other small electronic devices. These special K9 dogs have been used to detect tiny technology in order to reveal criminal conduct stored on these digital devices.
1) It’s not a secret. I’ve known about it for over two years. Tech equipment gives off an odor, too, and it increases with age of the product.
2) If a drug sniffing dog in an area without a reasonable expectation of privacy is not a “search,” how is this?
3) The sniff only reveals the item, it sure doesn’t search it. They’re especially useful in prisons and jails where cell phones are contraband.
