The ACTUAL TEST that PROVES something IS BLOOD was not done.

Well that makes absolutely no sense at all unless there was some justifiable reason for this. Does the other test positively identifying blood require more of a sample than what was available. I can't think of any other reason for not doing that test.

The test on the jacket was phenolphthalein presumptive blood test. Reacts falsely to potatoes and horseradish & aged reagent.

They also did no blood spatter analysis which would have told them under what circumstances the blood came to rest on a particular surface.
