Two men from different locations in the US, flew to Chicago and changed their flight plans to Dulles (Virginia) and on to Amsterdam to straight to Amsterdam. Inside their checked luggage were knives, box cutters, $7,000 cash, several watches and cell phones taped together. One of those electronic devices was taped to a Pepto-Bismol bottle.
This is indicative of the Bojinka Plot, wherein a an Improvised Explosive Device (IED) was hidden under a seat with a watch timer taped to a bottle about the size of a Pepto bottle. The Islamically-motivated terrorist got off the plane after hiding the device. The IED exploded in air and the terrorist was no where to be found since he got off that flight.
Evil men will continue to attack weak links (and all cannot be secured with perfection). Eventually another attack, and then another will happen.
My concern is that in the wake of another terror attack the masses will demand safety, but at what consequence? Instead of creating larger government bureaucracies and spending more money that we don't have, we need to pray for those in charge that they'll exercise wisdom and constraint -- that they'll preserve our freedom while preserving our safety. We, the people, must never allow our safety to take precedence over our freedom.
In sum, let's always remember the inspired words of Benjamin Franklin:
"Those who would give up an essential liberty for temporary security, deserve neither liberty or security."
Let us return to God and know that He directs the affairs of the people and He can stop attacks or allow them to occur where intelligence or security personnel fail.
