Racer, trust me, you WILL see another attempt to crash a commercial jet into a high value target on US soil. It is a given over the course of our lifetimes. You have not thought through the threat as it exists now versus the deterrent measures in place today, nor have you thought through the benefits of having armed pilots on commercial aircraft.
Why are you against arming pilots? They are there to protect the cockpit in order to survive and get the aircraft on the ground. They will not open the door while an attack is in progress, but they will have to fight whether they are armed or not should the door be breached. Just flying the airplane is not an option.
Do you also think that FAM's are superfluous? By your logic, passengers will save the day (you haven't thought through the issues on that either), assuming from your perspective that having the aircraft lost will all souls is a "success" somehow.
While you can't know the intracacies of the problem, it is obvious that there is much that is just being pushed aside without even basic familiarity. It seems that you are projecting the circumstances of the last attack versus the current remedies, not looking ahead to different tactics available to the bad guys...
