The US Supreme Court recently stopped the FBI from placing GPS tracking devices on vehicles without first obtaining a search warrant.
In a stroke of pure genius they decided to turn them all off before they got them back. And not they can’t find 3,000 of them.
According to the Wall Street Journal:
After the ruling, the FBI had a problem collecting the devices that it had turned off, Mr. Weissmann said. In some cases, he said, the FBI sought court orders to obtain permission to turn the devices on briefly – only in order to locate and retrieve them.
God bless America.
