Science in the Courtroom: Are they guessing?

Too often in the work I do, I have seen so-called scientists reach the most inexplicable conclusions, usually without any scientific basisfor their claims.  Here is another example of the forensic science community abandoning scientific method.  As a lawyer with a significant amount of time studying science as a young engineering student, I always break down cases in accordance with scientific principles.  If it is not good science, it shouldn't be in the courtroom, and if it makes it to the courtroom, it should be destroyed by the lawyer.
