A federal appellate court further ironed out the reach of the Fourth Amendment in today’s digital age, ruling the protection from unreasonable search and seizures does not apply to law enforcement’s use of wireless-tracking software through a third-party internet router.

A panel for the U.S. Court of Appeals for the Ninth Circuit ruled Monday that the FBI’s usage of software called Moocherhunter to find device addresses linked to child pornography did not constitute an unreasonable search under the Fourth Amendment since the suspect was pirating his neighbor’s internet.
