I've seen this mentioned a few times now, so I just did a quick google to see what's what. It's actually 144 people beheaded in Saudi this year so far, probably more as the article I found was published at the start of November. However, I guess the argument there is that at least they have a justice system, with proper police and courts and stuff. The sentence may be harsh for some things, like drug trafficking, but at least it's all set in stone and you have half a chance at defending yourself. With Daesh you get none of that, and they'll kill innocents just for the sake of it.
I don't think the Saudi system is one we should all aspire to, but neither do I think it's in any way comparable in terms of barbarism.
Quite right Dan ! I lived and worked in Saudi Arabia for over 2 years and I felt very safe and secure during that period. Yes, punishment is severe for people who commit crime, but the system means that nice people (like me) can go about their business without worrying that someone is going to nick their car, steal their money or knife them. One of the things I remember vividly are the jewellers shops with displays of gold, expensive watches, diamonds etc., all without massive security ...
