Unless I'm mistaken, that would be the same series of videos that claimed to debunk the burning of bodies in pits by hastily constructing a camp-fire in a hole and concluding it was impossible based on that fact alone, right?
Wrong. It's a series of videos of which one of them demonstrates how unrealistic body disposal at the AR camps would be by simulating the process using the leg of a lamb on a beach somewhere along the California coast. It's not a perfect demonstration because lambs aren't people and the snow and frozen earth of the Polish outback in the winter won't be found along a California beach any time of the year. Denierbud also cheated by not using fresh cut wood as a fuel source, IIRC.
It's an interesting demonstration for somebody who has never seen meat cooked on an open flame. However, anybody can demonstrate the absurdity of body disposal at the AR camps by holding a steak over a backyard BBQ until it catches fire and then remove it from the flames and see how long it continues burning on its own.
