So be it. At least we would have a fighting chance. Rather die in a fire fight, than be turned into a bomb to kill thousands of my fellow Americans.
First, being non-citizens, they would not be allowed to carry on domestic flights. I don't have a solution for international flights, but these were not international flights.
Second, even IF they managed to sneak a weapon onto the plane, and even IF they managed to shoot a passenger or two, their evil plot would NEVER have reached fruition and killed thousands.
Forget the billions of dollars worth of new ineffective security measures and forget billion dollar Airline bailouts. Arm Pilots and get a decent bulkhead door installed on the planes, and I predict no more deliberate plane crashes, and a renewed and improved sense of safety amongst the flying public. These simple, common sense, inexpensive measures would actually work. That is why the Government doesn't want to employ them. Not enough sex appeal, and definately not enough expansion of Government control.
Besides, the Sheeple will happily pay for and submit themselves to it: an opportunity which has not gone unnoticed and will not be missed.
