The quote reflects a critical view on the balance between civil liberties and national security. It suggests that in times of crisis, society often faces the tough decision of sacrificing personal freedoms to ensure safety. The author, Niall Ferguson, emphasizes that this dilemma is not new and has perpetually re-emerged throughout history.

Ferguson's message serves as a reminder to evaluate the implications of prioritizing security over individual rights. He implies that the justification of protecting the public can lead to a slippery slope where fundamental rights, such as habeas corpus, are compromised, ultimately questioning the integrity of democracy in the face of fear.
