One of the reasons I do not think this thing was an intentional framing is the testimony of Stefanoni with regard to 36B.
Stefanoni readily admits the problems with it. It requires four tersts, does it not? And all four are destructive tests, meaning that you do not get what you tested back.
Add to this that there was only a sufficient sample size, so she claimed, to do one test. She had the choice of finding the composition of it, or who it belonged to.
It was perhaps the only sound decision she made, she decided to test to see who 36B belonged to. That test said it was Meredith's.
Yet the standard is to do a second confirmatory test, and obviously she could not do that.
And here's the kicker.... What was it? It was Meredith's but what of Meredith's was it? This is BEFORE even considering the "too low" issue.... or the missing data that other experts complained about.
The testing did not reveal it, because there was nothing more to test - not to mention, that no one else in the universe has ever seen the so-called-crevice in the knife which it was supposed to have hid to escape cleaning.
If THIS is the frame up, it is the most incompetent frame-up in the history of crime.
