That dude doing the course is not a scientist, he's just a local firefighter with experience. He hasn't done wide scale tests of his theories on a major level following the scientific method. It's pseudoscience. And you trainees have no bones to qualify you to testify on any of this. You are not a scientist, you are a public servant, these are not the same. And it's terrifying when one considers that literal lives are at stake. Your proposed method of expertise had been proven wrong and exonerated time and time again. The American public deserves far, far better methods, based on science, than what your post literally proposes. People are executed over this joke of a science.
