I agree. I don't think we should intentionally scare people, and I don't think we should try to dwell on the negative.
I do think we should be open an honest about the truth though NN. People asking questions and hitting a "if you aren't willing to take the risk, don't go forward" line isn't the best approach in my opinion.
No one is witch hunting, but this is a place where we can ask open questions and get the open truth, unless I'm wrong. If Dr. B made a mistake, he should own up to it. Pat should check it out and tell us what he found out.
I've seen other reputable Dr's do that, like Dr. Hasson. He did surgery on a patient that he admitted he shouldn't have. That doesn't make him any less reputable... in fact, in my opinion, it makes him more reputable, because now we know exactly what went on with that situation.
Let's not dismiss people wanting to know the truth.
