If you think technology can solve your security problems, then you don't understand the problems and you don't understand the technology.

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.

Technical problems can be remediated. A dishonest corporate culture is much harder to fix.

Terrorism is a crime against the mind. We win by refusing fear.

The question to ask when you look at security is not whether this makes us safer, but whether it's worth the trade-off.

Microsoft made a big deal about Windows NT getting a C2 security rating. They were much less forthcoming with the fact that this rating only applied if the computer was not attached to a network and had no network card, and had its floppy drive epoxied shut, and was running on a Compaq 386. Solaris's C2 rating was just as silly.

We can't keep weapons out of prisons; we can't possibly expect to keep them out of airports.
