He he...though keep in mind that it IS a crime drama, so there are mistakes, but for the most part, I'm sure they go for an accurate portrayal, since there are people (such as the Talk:CSIers..) who pick up on the mistakes!
Anyways, I've learned that "it ain't over til it's over", meaning that "don't give up on something just because there doesn't appear to be an easy solution or explanation".
