seems to me after reading this BBC news report
BBC NEWS | UK | Mandatory DNA database rejected which states there is a database of 4.5 million allready on file that its a bit to late , considering that the 4.5m and by simple extension also includes the parents and any sibling (brother or sister) its a bit late to start worrying ...........kind of surprising considering all these controls have been instituted by a Labour Govt. and not by the 'right wing' fascist Conservatives , maybe 'nu-Labour' has more in common with Stalinist Russia than anyone thought.
