There is a lot of ink being spilled on what is really a pretty minor technical change. The FBI can break into your house so long as it gets a search warrant. So why shouldn't it be able to hack into your computer with a warrant too? What the rule changes do is just change the jurisdictional requirements for obtaining those warrants. Those changes make sense: the FBI may have no idea what district a particular computer is in. Under those circumstances, the rules permit the FBI to get a warrant from a judge in any district.
