There is an excellent article on the Social Affairs Unit blog called Civil liberties cannot be defended selectively, by Joyce Lee Malcolm.
As the culture and meta-contextual assumptions of liberty have decayed amongst the intellectual and activist elements of British society, the institutions supporting liberty for so long have been revealed to have no foundations and are thus unable survive the torrent of events such as Hungerford or even the 9/11 terrorist attacks in another country.
As the Joyce Lee Malcolm article points out, the so called ‘opposition’ and even the vast majority of the media have abdicated their role in seriously questioning the disassembly of ancient civil rights for decades, whilst the rights to self-defence, trial by jury and double jeopardy are steadily abridged. It is hard to avoid the conclusion that the British system, which for so long survived and thrived by using the custom of liberty as its bedrock, has shown its fatal weakness. Defending civil liberties in the UK is becoming harder and harder because not only have the institutional means for doing so been effectively swept away, so few British people even understand upon what their now largely illusory liberties were based.
