For if we are observed in all matters, we are constantly under threat of correction, judgment, criticism, even plagiarism of our own uniqueness. We become children, fettered under watchful eyes, constantly fearful that-either now or in the uncertain future-patterns we leave behind will be brought back to implicate us, by whatever authority has now become focused upon our once-private and innocent acts. We lose our individuality, because everything we do is observable and recordable.

ID can be hijacked, and cards can be faked. All of the 9/11 terrorists had fake IDs, yet they still got on the planes. If the British national ID card can't be faked, it will be the first on the planet.

Why is it that we all - myself included - believe these stories? Why are we so quick to assume that the TSA is a bunch of jack-booted thugs, officious and arbitrary and drunk with power? It's because everything seems so arbitrary, because there's no accountability or transparency in the DHS.

It's certainly easier to implement bad security and make it illegal for anyone to notice than it is to implement good security.

Anyone, from the most clueless amateur to the best cryptographer, can create an algorithm that he himself can't break.

Security is a process, not a product.
