Why do some people believe there is a link between Jack the Ripper and Freemasonry?

Franklin Ruehl (Author - Anomalist) gives expert video advice on: Who are the Freemasons?; What are the origins of Freemasonry?; What goes on during Freemason meetings? and more...

The ritualistic killing of Jack the Ripper, and we always hear there were five, there might have been a few more before they were identified with one individual. But the way the bodies were just mutilated, it makes one wonder if there was some type of ritual going on, and not just a madman at work.At one of the killings there was on a wall “The Juwes are men that will not be blamed for nothing.” Originally it was thought that this was some reference to Jews, but Jews was spelled J-U-W-E-S. Another theorist said it was actually some link to the Freemasons. The police chief at that time had that erased from the wall, ostensibly to prevent any backlash, anti-Semitic backlash. But it might have been actually because he was a Freemason, he was trying to hide this link to the Freemasons.
