Yup.
JG kept trying to get the witness to agree that his field is just art...not science. I was thinking Greer could use a medical doctor as an analogy, indicating that even medicine, considered a science, has some elements of art, but that doesn't mean you can't get a diagnosis.
Then is re-cross by prosecution, Greer indicated that there is much to learn not only in the program, but through experience on the job, "kind of like an intern in medicine". JG bolted up out of his seat, but was quickly overruled. LOL
