On why DNA isn't everything

In light of the comments from this post of mine a few days ago, I thought readers might appreciate the problems associated with over-reliance on DNA in criminal cases.  As this article at HoustonChronicle.com explains, the DNA evidence can be fudged in various ways, and the consequences for the wrongly convicted can be severe.  Of course, this doesn't mean that DNA evidence shouldn't be used or should be categorically discredited; it's probably the best evidence one can hope for, and it is capable of illustrating the follies of other sources of evidence, when deployed properly.  But as long as women and men are involved in the administration of criminal investigations and prosecutions, there will be room for error, or worse.    (Thanks to loyal reader Ruchira Paul for the article!)
