The same discussion should bring out that the sort of arbitrary, unlimited data-sharing of the kind hoped-for (not, definitely not, “envisioned”) by government will almost always be exposed to the charge… unless it is deemed that when anything is done for official purposes or under official procedures that is automatically a reasonable excuse. Which is really the core of the government’s authoritarian ethos (not quite the right word, but “thinking” definitely isn’t): Officialdom is above suspicion; everyone else under it. The availability of severe punishment for those deemed bad constitutes order. Coherent law and principle are in the way.
