I don't claim to know what happened, LH. I just want a real, scientific investigation to determine what happened. I think that's a reasonable stance to take. Other people feel threatened by this stance and feel that they need to make those of us who adopt such a stance out to be "conspiracy theorists", non-rational, and stupid (all terms that have been used by such people here in this thread. I don't see any reason why such people should be allowed to have the last word. I also don't see any reason why they shouldn't provide valid and verifiable evidence to support what they are saying, when asked to do so.
