"For obvious security reasons, we can’t discuss our technology's detection capability in detail"

Security through obscurity.

Are they afraid that if they disclose information people would somehow be able to find holes? If this is the case then why is this technology used? Why have gapping holes already been pointing out by numerous people?

Thinking that "the terrorists" don't have the ability to break this system without understanding the intricate details of it is just downright stupid.
