The PJ were not aware at the the time that it was inconclusive, but it remains the fact that the DNA strands did match Maddie.
The PJ were fully aware that the test was inconclusive when they leaked the info to the press and from memory that particular leak may well have led to Amaral's sacking.
The DNA sample also could have matched thousands of people - possibly both you and me.
Stop being disingenuous.
