Doug, I don't know about the well publicized part. Hey how many people out there do you think they have who can fly a jumbo and are willing to commit suicide. That's why it takes years between each terrorist attempt, just not that many capable people are willing to kill themselves. Jihad or no Jihad. If we don't publicize our defences then we have a better chance of catching them. Deterring them may just mean they choose a different unwatched avenue!
