I think this is a reasonable place to draw a bright, red line. It'll make us look unreasonable if we act unreasonably. What's really harming us is that we don't have a formalized value system from which to engage in rhetoric, nor do we have a standard rhetoric which people can easily engage from and against.
We already have enough mass surveillance devices. But I suppose two arguments could be made (1) we don't need more of these, or (2) peak surveillance has already been achieved, and adding one more doesn't make any difference.
