Securicor: carried out US Sept 11 airport duties properly

Securicor repeated its assertion that its US arm Argenbright carried out its airport screening responsibilities "properly and in accordance with its contractual and regulatory duties" on the day of the Sept 11 attacks.

The comments come in a retort to legal claims holding Argenbright at least partly responsible for September 11 terrorists slipping unnoticed past the firm's security checkpoints at two American airports.
