From the OS -
'Disclosed paperwork shows that there were two moderators being examined on the same day, each with different contaminates and having different characteristics. This means that we can be certain there were two.'
-----------
Are the OS saying the police fabricated two moderators. Then submitted both to the lab team at different times. One with blood in, one with paint on. Then asked the relatives to say they found one moderator?
The lab team examined two moderators on the same day & merged the results to relate to one moderator. Meaning they are part of the industrial frame.
