sherlockh, Fulcanelli, and others,Again, you just point at the scientific part. There is no point in that. I already explained that there is a difference between scientists and judges. If the scientific part is not conclusive then judges are free to use their own reasoning (by putting things in context for example) and to draw their own conclusions. It is not unusual. In fact, that is their job.
Everthing I have said or quoted is in the context of forensics, which some define as "the application of science to the law." With respect to luminol, draino, rusty water, and some cleaning products are capable of providing a false positive. If one believes that they were set in bloody water, how about explaining how and when they were made?
With respect to the Kastle-Meyer test, it is very difficult to see how one could apply the hydrogen peroxide quickly enough over the area seen in the photo. One only has five seconds or so: "A positive reaction is indicated by the development of a pink colour within 5 seconds. Reactions occurring after 5 seconds, or before the addition of the hydrogen peroxide are inconclusive. A pink colour after phenolphthalein has been applied but before hydrogen peroxide has been applied normally indicates a false positive due to an oxidising agent being present. Rust could cause a false reading of this type."
