The continued determination of the British state to hold on to the DNA of innocent people in the face of huge opposition reflects the tenacity of a certain mindset. This same mindset insists that the intrusive and expensive positive vetting of anyone who comes into the slightest contact with children is the only way to protect kids from potential abusers. The fact that it patently does no such thing and effectively brands everyone as a criminal unless they can prove they are not, thus breaking the fundamental rule of justice: innocent until proven guilty, is answered with a shrug. Even so fundamental a rule should surely be ignored because "the kids" must be protected at all costs.
This is the way to total subservience to the state. Instead of society being based on a fundamental contract amongst free citizens, there are now large new areas of law which demand complete obedience. Whether the insulting anti-paedophile laws or the draconian anti terrorism laws, the last few years have seen a huge extension of state power. This power has not only come at the expense of the rights of individuals, but also at a huge financial cost too. The costs of administering the mechanisms of legal intrusion and economic dependency have turned Britain from one of the cheapest countries to administer into one of the most expensive- and this fiscal drag is undermining our economic competitiveness dramatically.
It is not just a matter of the moral benefits of freedom, the costs of the creation of the suspicious, and snooping society so beloved of Labour apparatchiks are well beyond our financial capacities too.
