Today, the talking heads and the television newsies spent the morning (on all channels) seeking to torture from the language an assurance that air travel for the public (read themselves) could be made 100% safe from ANY sort of attack devised by devised by "fiendish" jihadi minds. This goal was never quite reached. John Brennan, the president's terrorism man, was not so foolish as to give an assurance like that.
No security system devised by the mind of man can be 100% secure against the minds of other men. There will always be some chance, however slight, that your perfumed hindquarters may be in a first class seat when the cry goes up, "Allahu !Akbar!" and that could be the last thing you ever hear. Polticians can fuss and slander each other. Consultants can continue to make seas of money working on airline security, but the possibility will always be there.... "Allahu Ak..." (Apparent silence, perhaps replaced by a rushing sound on the way from 30,000 feet to the surface)
Sooo, do you really want to travel by air? Bin Laden reckons that you don't, really... but that greed or circumstance will force you to continue and that being the case he has gotten a tremendous "bang for the buck" in this operation. He will continue with this line of endeavor, and hopes that you deploy a few hundred thousand more troops to places like Yemen. pl
