 If you had me wire a house as an electrician, I'd burn it down. If you asked me to do the job of a plumber, I would know hot from cold. I know what I know, and I know what I don't know. But if I'm using information provided by somebody else, so forth, I would say, plumber XYZ told me, good guy, that's what we do. No, it doesn't work that way, apparently, anymore. This is basic ethics.
