I saw that video clip. What he said was more like: "We're on track to reduce the world population by 50% by 2023."
In such a case, I fully support his capture and intensive interrogation for whatever info he has to that effect, by whatever means necessary and available:
-- waterboarding, battery cables to sensitive body parts, ants and honey, crabs in the water tank.
Enough.
The actual quote, before editing was:
“We’re on track to reduce the world population that does not use Pfizer products by 50% by 2023.”
