I think Jack-the-Ripper was an Arab diplomat, maybe from Lebanon or Egypt. His behavior would be in line with what we see from Muslim sheiks but embarrassing to the Al-Fayads types who own Harrods and now half of England.
Big problem with that idea - there were no Arab diplomats in the UK in the 1880s. Britain simply did not exchange diplomats with the Middle Eastern nations. There were some Muslims (the first Mosque in the UK seems to have opened around 1886) but it was a small number and they were mostly from India and surrounding nations.
