Religious doctrines and borders led to the Ripper roaming free

In 1888, the most infamous murders of all time took place in London’s East End. Five prostitutes, destitute women who knew of no other way to survive, were slaughtered and/or mutilated by a supposedly unknown killer who bears the nickname Jack the Ripper.

The identity of the killer is controversial and many believe the right man will never be named.

The best judges are those who may have had knowledge that has been lost to us.

Assistant Chief Constable Macnaghten, Sir Robert Anderson and Chief Inspector Donald Swanson certainly claimed to be in that position! 
They all blamed a Jew.  Anderson said he was protected by his co-religionists from "gentile" justice.
Religious suspects include Aaron Kosminski and Baptist Pastor John George Gibson. The latter may have committed murders in his Church in Los Angeles in later years.  The Ripper killings had some religious hints with the marks carved on Eddowes, hatred of womanhood as in attacking the sex organs and prostitutes were targeted though there were plenty of drunken women available.  This was like a man trying to bring divine vengeance on a certain kind of woman.
