More scary DNA ramblings...

A story in The Guardian today gives more information about the DNA samples the police are allowed to collect. Now, call me a hoary old conspiract-theorist (I love it when you use the word 'hoary', it sounds so dirty!), but is one were to take these DNA samples, and, for example, cross-reference them against the results of a compulsory questionnaire issued to every household in the country, giving a number of personal details (Let's call it a 'census'), then that might prove to be quite an interesting and rich data source, mightn't it...?
