Judge: The jury have returned their verdict and you have been found not guilty of all charges. I therefore sentence you to twelve years of suspicion; twelve years of wondering if there might be a knock on the door if you happen to have been near a place where a crime was committed; twelve years of being an automatic suspect for every new crime investigated.
This is what the ruling to retain DNA samples of people not charged or later acquitted of crimes means. The Home Secretary said “We will ensure that the most serious offenders are added to the database no matter when or where they were convicted” but these people were NOT convicted; in many cases they were not even charged.
There is talk of them extending the 6/12 year limit to fingerprints as well, but we know that is a joke—everyone’s fingerprints will be on the National Identity Database anyway.
