Going to other extreme: I always wondered why everybody's fingerprints were not on file: what a weapon in the fight against crime, I always thought. & what would the innocent have to fear?

People would scoff when I said this; but I was never convinced by their arguments. They would also say that the over-filling of the system would make retrieval a near-impossibility. But now, with computerised facilities for storage & retrieval, & replacement of dabs by DNA as identifier, I revert to this position. If all our DNA were available, the hints & accusations of racial invidiousness would disappear & we should all start with a level playing-field [as the cliche-metaphor has it]. I have no intention of committing any crime, & they can come & take a swab from me any time they like.

What does anyone think about that?
