|Airplane allowed knives|
Most other places in Europe allow their passengers to carry small knives, but after 9/11 american tightened up because we thought banning blade would make the flight a safer place.
Before 9/11 no one even considered using a box cutter to take over an airplane so it worked and american wont be duped again....
The big issues are a little difficult to nail down...on the one hand allowing pocket knives will keep the securities attention on more dangerous things (like bombs).
If everyone has a knife then it is less likely for someone to attempt to take over the plane with only a knife..
On the other hand.....
The flight attendants do not want this to happen. They have to keep their clients safe, quiet and satisfied. Imagine an angry person stuck in a confined space for three hours. Now add in a crying child and a stupid in flight movie....this person is not close to thinking about using any object to inflict bodily harm.
It seems humans will be pre-screened in order to pass through security...how much information will the airport security gather? Will they share all that information with foreign countries?
There seems to be a slippery slope with "pre-screen"
