Recently watched the Netflix docu series on this, J&J claimed that cyanide was not present in the factory, so there is no way the pills could have been contaminated at the factory.
Then later on one of the doctors asked J&J if a test for cyanide is done for each batch in QA at the factory. J&J said yes, each batch was tested for the presence of cyanide.
The doctor then asked, "Why were they testing for it(cyanide)?", kinda blew my mind. Implying that J&J knew cyanide contamination was a possibility at the factory itself.
