Just because something says 'Helter Skelter' doesn't mean it's real

For the most part I like the documentary besides the beginning with the narrator showing off his box of rubble, but one thing I hated was everywhere he sees the words "Helter Skelter" he claims the Manson family did it. He said hikers and people stay at the Barker Ranch and places around it and maybe one of them did it.
A lot of the documentary was good but he gives way to sensationalism and storytelling and a lot of times that hurt a documentary's credibility. It was good and I applaud his efforts but there are brief moments where he almost seems to admire the Manson family activities and he has set up a business busing people around viewing celebrity death locations. Kind of hard to take the guy seriously when he wears a hat with his business all the time as if going for free advertising.
