In my opinion it is the height of naïveté to assume these changes are being made to enhance security of the individuals involved. It will be used to deny providing information on when and where taxpayers are put on the hook for these people’s travel.
Frankly, I prefer to politicians live in fear of the constituents, than part of another caste, above and beyond letting the hoi polloi know what they’re up to.
I do agree with one thing. A fearful politician makes for freer population. But not all fear is equal.
