Spy technology failed to signal attacks
Quote:
The attack on the U.S. Tuesday
took intelligence services by surprise, despite technology that allows monitoring
of almost all communications worldwide.
A global electronic surveillance network,
known by the code name Echelon, failed to alert the intelligence services of the
terrorist attacks. U.S. officials have never officially confirmed the existence of
Echelon, but an investigative committee of the European Parliament recently concluded
that the spy network is real.
Technology is not a solution, Elly Plooij-van Gorsel,
who served as vice-chairman of that committee and is a Member of the European Parliament
(MEP) from the Netherlands, concluded Wednesday.
"Intelligence hasn't been able
to intercept the communication of these terrorists, intelligence has failed," said
Plooij-Van Gorsel.
"Echelon can intercept any communications worldwide. If there
have been phone calls or faxes, this system should have intercepted it. If there
have been communications, it was done under a cover of encryption or by old-fashioned
courier," she said.
"Echelon hasn't worked. In the coming days there will be a
lot of discussion about whether the intelligence services have invested in the right
technologies. Perhaps they should have opted for spies, for human intelligence,"
said Maurice Wessling, a Dutch privacy and digital rights activist.
