Under the old version of “Rule 41,” agencies like the FBI needed to apply for a warrant in the right jurisdiction to hack a computer, presenting difficulties when investigating crimes involving suspects who had anonymized their locations or machines in multiple places. Under the new version, a federal judge can approve a single search warrant covering multiple computers even if their owners are innocent or their locations are unknown.
So, who cares about innocent until proven guilty? Or probable cause? Or mass surveillance and breach of privacy? Or security for your own devices?
