Thanks for posting the evidence according to the Saudi authorities. I have to look more closely at it, but it appears the man is still not being convicted of doing sorcery in Lebanon. Rather, he is accused of committing fraud and conspiracy to harm people using "sorcery", on Saudi territory. That is different from what I thought was the case, but there are still problems.
First of all, I'm concerned that the Saudi religious police engaged in
entrapment. Second, though it would not surprise me if he was a fraud, in that case he can't be a sorcerer, so his offense was deception and taking someone's money, and the punishment should fit the crime. Third, if this TV host truly is a dark wizard a la the Harry Potter children's books ...
... then he can't be convicted of fraud, and he can't be convicted of conspiring to cast evil spells without solid, scientific proof that he actually has this power.
