I am happy to be corrected if I am wrong, but I believe that the Home Seceratary David Blunkett authorised the carrying airside of the Sikh's religious dagger. The same guy who is trying to cover his backside by introducing a lot of ineffective extra security measures which had immeasurably more to the hassle and not much to the security of the environment many of us work in. I have said this a couple of times before I am 100% for effective security just 100% against futile gestures. Sadly I believe that this case will lead to more of the latter.
One thing that this case does highlight is the need for the crew to be trained to a sufficient standard to carry out a thorough cabin inspection.
