If everyone had their DNA taken at birth it would remove the discriminatory effect of the current system where police are able to take and retain DNA from innocent people. However, it would introduce many more, such as that highlighted by EDDIE. I’m glad to hear that your o/h does not allow such prejudices to interfere with his recruitment processes. Alas it is not universal.
I’m afraid the “If it saves one life...” argument is too tiresome to consider. There are many things that would save considerably more than one life. We could, for example, prevent anyone from driving a motor vehicle, saving around 3,000 lives per annum. This is neither practical, nor desirable and is disproportionate, even with a saving of 3,000 lives.
I (and I believe many others) find it extremely disturbing that many people are sufficiently trusting to allow the State to hold ever more personal information that they simply do not need. This is especially so in view of some of the major breaches of security that have taken place over the past couple of years that have adequately demonstrated that State organisations simply cannot be trusted to handle such information securely. For its own part the government goes to great lengths to educate people on the perils of identity theft, but actively encourages its own agencies to gather unnecessary information and retain it.
I’m sorry you’re offended by my description of such trust as naivety, but I really don’t know how else to describe it.
