I wonder about this all the time.
Sometimes I comb my hair, or bite my fingernails. What if part of it fell on the floor and some random person steps on it. Stuck on the bottom of their shoe. A bunch of coincidental stuff comes up and my DNA is tested against a fingernail/hair under victim's shoe... match. I'm doomed.
Indeed, I fear the mentality that DNA-match = Guilty.
How many people have been sent to jail/put to death based on false DNA results or even accurate but not via the crime they're accused of.

A bunch of coincidental stuff comes up and my DNA is tested against a fingernail/hair under victim's shoe... match. I'm doomed. This is a plot point in the film Gattaca. I'd recommend watching it if you haven't already: http://en.wikipedia.org/wiki/Gattaca http://en.wikipedia.org/wiki/Gattaca

A normal person will lose 50-100 hairs every day.[0] Also, everyone sheds dead skill cells, and certain dermatological conditions can exacerbate matters.
