Thanks for considering the matter Karl I feel so many things are drawn from a relatively small sample when one considers the opportunity and although reasonable in the case of the possibilities raised by identical fingure prints or DNA still because one has not sampled all that there is to be sampled the "test" becomes a rule rather than a possibility. A poll is an extreme example where the views of perhaps millions of people are concluded from a sample of the views of a mere 1000 or 2000 people. I hope a lawer does not get hold of the "snow flake"thing to throw DNA evidence out of court.
Thanks again.
