The difference between scientific method and police investigation.

DNA Work Flow




NOTE:  This is not an original work.  It is compiled from the sources listed at the end.  It is intended as a basic starting point in defending cases involving DNA evidence.

“DNA evidence, at best, can only tell you whose DNA you’re probably looking at. It cannot tell you how it got there, what happened, or who did it. And just because the DNA may even probably be your client’s, that doesn’t mean he necessarily did the crime. Just like with a fingerprint, there needs to be more, a lot more, to tie him to the commission of the actual crime. People forget this. And all the DNA witnesses can do is evaluate their data; they cannot evaluate the case itself.
