The sentence "Screw that" is actually the core of your argument. Why not spy on "folks" (are you a politician? :D) at home? Their power of voting and free motion within your whole country actually makes them much more dangerous to your safety than any foreigner can be.
The reason why they won't be so easily spied on is not "screw that", it's because they are voters. Not because spying on voters is wrong - but simply because they can change the government when they get annoyed! So, as it is meant to, voting protects the human rights of a population.
But it would be nice if that population would actually believe in human rights. Particularly if they want to portray themselves champions of the matter. But if your attitude is an example, "screw that", huh?
