YouTube link to indie documentary Tread about the 4th of June 2004 “Killdozer” incident in Granby, Colorado (U.S.)

Making a separate post for visibility and due to interest in the event seen in the discussion thread, also being 20 years exactly since it happened. It’s a captivating and well-made film, composed of a mix of historic footage of the event, high quality live re-enactments (I usually dislike those), Heemeyer’s audio diary tapes, and interviews with the people targeted by him.
