It's a very sad indictment and reflection on the insidious ongoing brainwashing perpetrated by the UK government, all under the cloak of 'the war against terror' that this question even has to asked. This isn't East Germany under the Stasi but still (for how much longer?) a free and democratic country. There are, undoubtedly, 'sensitive areas' that may be of interest to some unscrupulous individuals and merits a degree of privacy from prying cameras but does it really matter whether you snap the passing 767 (I take it we are talking about aircraft photos here) from 6 inches outside the airport perimeter fence or inside it - of course not.
