I can't imagine a country where 80% of the population is against abortion, and it still would be legal. In some indirect way law reflects what a population wants. Even the constitution can be changed with enough votes in parlement (at least in The Netherlands, US I don't know). So the question is still open, is there any legal ground in what the FBI is asking from Apple? And if there is, should the cooperate? And what would be the alternative, leave America?
