Why shouldn't pilots accept the introduction of ID cards for the highly sensitive areas in which they regularly work? For a very good reason:
It seems a reasonable request on the surface, which once established will then be rolled out to another section of people in this country. This will carry on until the meglomaniac government gets its wish of every Tom, Dick and Harry having an ID card just because it suits the intrusive and frankly bloody nosey government/police/security services we have in this country! Before you know it you'll be required to produce your ID card for things you woudn't credit it being reasonable for at the moment.
N.B. Churchill abolished ID cards in 1952, sighting them as a menace to the public good. A motorist refused to produce his ID card in 1950 when stopped by the police for no stated reason. When the case went to the High Court, the Law Lord presiding made the following statement, which is as valid now as it was when it was made in 1952:
"it is obvious that the police now, as a matter of routine, demand the production of national registration indemnity cards whenever they stop or interrogate a motorist for whatever cause. Of course, if they are looking for a stolen car or have reason to believe that a particular motorist is engaged in committing a crime, that is one thing, but to demand a national registration identity card from all and sundry, for instance, from a lady who may leave her car outside a shop longer than she should, or some trivial matter of that sort, is wholly unreasonable. This Act was passed for security purposes, and not for the purposes for which, apparently, it is now sought to be used. To use Acts of Parliament, passed for particular purposes during war, in times when the war is past, except that technically a state of war exists, tends to turn law-abiding subjects into lawbreakers, which is a most undesirable state of affairs. Further, in this country we have always prided ourselves on the good feeling that exists between the police and the public and such action tends to make the people resentful of the acts of the police and inclines them to obstruct the police instead of to assist them"
P.S. I'm a law abiding, tax paying, conformist member of UK society. But of course you'll be able to confirm that if ID cards are introduced, because you can be sure the system won't be secure (even the CIA central computer isn't secure remember) thus meaning once the government completes the donkey work of collecting the data, it will be lost/stolen and then appear on the internet to the highest bidder!
Happy days....
