OK, I'll throw my two cents in (altho as comedian Steven Wright notes: "Why is it a penny for your thoughts, but you put your 2 cents in? Seems like someone is making some money off this scam..."
I am a scientist (in my opinion). I just happen to also be a fingerprint examiner. Being a fingerprint examiner doesn't make me a scientist. Performing comparisons doesn't (per se) mean I am a scientist. To me it's all in the application. Here I agree with Michele's previous writings that how one applies scientific method and lives, breathes, eats, sleeps sci method and asking questions, testing hypotheses, etc...that's the science.
I can see a continuum where on one end some exams are so routine and automatic, you barely need a human: lights out afis type situation, where the computer literally counts minutiae and you monitor the computer. That's a technician. On the other end, I can think of cases where the distortions are so complex that you need someone like Alice Maceo, or Josh Bergeron, recently Michele for her "is it a scar?" case, etc. to test hypotheses, collect data, and draw conclusions about what hypotheses are supported and which aren't to continue to weigh your evidence, make inferences, and reach a decision. THe McKie case comes to mind. I read a lot of testimony from technicians playing "scientists". For me, Arie Zeelenberg truly stood out as a scientist, b/c hypotheses were generated about the cause of the distortion, and he actually tested them. He brought experimental data to the table with videos showing effects from distortions that were not supported by the 66 counter clockwise twist theory. That's a scientist bringing science to the examination.
I have no problem with 95% of our basic casework being essentially a highly technical skill and performing technician like duties (hey even doctors fill scrips and due routine "non-doctory" stuff and it doesn't make them any less of a doctor). But in those 5% of cases where significant understanding of how we make decisions, how we apply scientific method, how we test our hypotheses, assess risk, cost/benefit, etc. That's where I think the real science is. ANd I don't think all examiners recognize that or apply it the same, so as Michele has pointed out in her "Etiology..." paper, not everyone is doing this as a science (especially in those cases that need it).
Lastly, when it comes to Daubert (Bill S. mentioned where some of this push came from)....THAT IS WHERE I want the scientist testifying. Defending the science. One who understands the science, knows the research and it's limitations--what it supports and doesn't. The last thing I want to see (but do) is a technician spouting dogma, playing "scientist", and couldn't be bothered to read papers and research b/c "he/she knows it when he/she sees it practicing their infallible method with zero error rate". Here is where unfortunately, i think we need to parse out the technicians from the scientists. And frankly, most people don't want to do a Daubert hearing, so why not separate those issues out...keeping the technician focused on how they do their job (and they do it exceptionally well), following SOPs, etc. and let scientists handle the defense of the science.
Probably not the most popular view on this, but well... just putting in my 2 cents (although it probably was only worht a penny)

(and that's why I think agencies should allow their scientists (and technicians) to voice their scientific (technical) views and be able to share publicly their knowledge without having to go through a spokesperson, legal department, or get supervisors permission to post on a public chat board dedicated to scientific (and technical!!!) issues.)
