Share Dupont-Teflon Documentary The Devil We Know and Movie Dark Waters – Both showcase powerful people who stood up to DuPont -for us ALL! By Ayda Walsh Today we watched a documentary called the Devil we know on Netflix. It is very sad to see how the corporations as well as the government agencies such as the EPA do not seem to care about people and only about profits. We later watched it in a MOVIE format on Amazon Prime called “DARK WATERS” – excellent movie!
