We get to continue to derail this thread? AWESOME.
Of course I'd quickly be dismissed from this chiropractor's jury (not that he had a trial), and hindsight is always perfect, but I think I'd have a hard time letting him off so easy even if he didn't kill my uncle. If you claim to be an expert on backs, then at some point in your career, you should have heard that heart trouble can manifest itself as upper back pain. And if a long-time patient who only complained of lower back pain arrived suddenly complaining of upper back pain, then you refer him to the hospital. He came to you because he thought it was just his back, but a person who calls himself a "doctor" and claims to cure things should have that much knowledge of the human body.
Please continue to accept my apologizes for hating this thread.
