If pressed, I would have guessed that parent-child communications fall into that constitutional sweet spot, theNinthAmendment, which acknowledges rights so sacred they don't need to be enumerated.
More important, as Judge Callahan explained, theNinth Circuit had previously rejected the notion that computers should receive more protection under the Fourth Amendment simply because of how much data they store.
In conclusion, this recent Ninth Circuit decision should give pause to individuals planning to use the Fifth Amendment protections to oppose government subpoenas of records of offshore banking activity.
