This is more like the FBI asking the storage unit owner to turn off the security system that he installed that incinerates the contents of the storage unit when someone tries to pick the lock, but only on the unit that the FBI has a warrant to search. The storage unit owner then responds that although he could put an off switch on that particular unit, it's an outrage and sets a horrible precedent that the police should ever ask him to turn off his security incinerator.
