Does using drugs in the past suddenly mean presumption of innocence doesn't apply and you are guilty without trial?
Look, this guy dumped the sheikh's son and planned to leave the country. Then he was arrested based on a tip from a "reliable source" and it was claimed meth was found on him. This was never proven with any evidence, he was put into jail, spent many︀ months in there, then was sentenced by a judge where the entire process was: "walk︁ into the court room, stand for 5 second, judge says "Arthur, guilty, lifetime sentence, out",︂ and you are put back into the prison.
Probably his major mistake was that he︃ signed a document in Arabic where he admitted his guilt.
He was sentenced to life,︄ spent a year in prison, then the sheikh released him for reasons probably known only︅ to the sheikh and his son. Here's some more info:
Chora miłość szejka – Artur︆ Ligęska skazany na dożywocie w ZEA (again with auto-translate). If he's making all that up,︇ then he's a better story teller than H.C. Andersen and Agatha Christie combined.
By the︈ way he was next
cell next to Amhed Mansoor, what presumption of guilt would︉ apply to this guy then?
