I understand, maybe I was harsh to go off on your post. I think it was just the one that "broke the camel's back" regarding a lot of previous, ridiculous un-informed posts.
But a re-design based on speculation seems a little extreme to me. If anything, maybe it belongs on its own thread, because there is certainly no evidence yet in this one that deems a "re-design" is a solution. Maybe that might be the case as it was in the Roselawn tragedy (it certainly doesn't take an expert to find similarities in both), but I really think it is premature.
Anyone can make observations, that is all we are doing here. I just wish that wanna-bes would start their own forum and post there, or at least only read topics that they don't understand as opposed to offering their expert opinion with terminology whose meaning they don't really understand.
