Dr. Michael Yeadon : PCR Test "not suitable at all" "and I've worked in this field"

Dr. Michael Yeadon, former Chief Science Officer of a Big Pharma company (Pfizer) talks about the PCR test being used for Covid..
"Not able to detect whether the viral RNA has come from a living virus or a dead one"
"This test has never been used in this way; and I've worked in this field"
"It's not suitable at all, and it definitely shouldn't be done in the way it's being done"
"It's subject to many mechanical errors - shall we say - handling errors"
"If this was a test being used for legal purposes, for forensic purposes, like a DNA/identity test -- the judge would throw out this evidence and say it's not admissible".
"It produces positives even when there is no virus there at all; we call that a false positive"
"Cease mass-testing of the mostly-well in the community, immediately"
