I was amused to read that two Daily Mirror journalists where arrested when 'testing' security procedures on London Underground. Whilst it they say that they have a 'journalistic right' to expose security holes I personally think that it's just another type irresponsible disclosure where the people concerned don't have a chance to put right the problem before it's widely reported.

On another completly different note I was browsing You tube earlier today and found this fantastic clip of Bill Bailey and his rendition of the BBC News theme tune
