I recall it being a topic sometime around this discussion. maybe I am wrong. One idea is that evidence of crimes is pulverized and hidden in concrete. This code was half-literal in its effect. As to say, all evidence of pedovore crimes needs to be disposed of according to their disposal plans, which included hiding things in concrete. This of course could be way off. So the false flag is to remove the human-remains / bone chip containing structures before they are analyzed. Yes, very crazy.
