I've seen the supposed pictures of it, seen others that just show a simple rope with no knot, lot of stuff out there being passed around by media and memersThere has to be more to the story. Nobody recognized a pull down? The FBI had to get involved and even used the word noose in their report?
If it truly is that simple, then you know, kudos for someone recognizing that hey, this may not be right. It did seem to get blown out of proportion looking back, but maybe its better to recognize that people are being aware and culturally sensitive to others.
fwiw Bubba was interviewed and was asked if that knot (or others like it which require a bit of time and patience to properly tie) is a common sight - he said no
(as an aside, an actual noose knot is very different from a hangman's noose, with the former being a base for a canadian jam knot or arbor knot)
