. Jailed pending a trial is pretty harsh. Of course I can't speak for Norway, but it's usually reserved for suspects that pose a flight risk (Not that kind of flight. The fleeing kind.)
In Norway a suspect goes to custody for max 3 days awaiting trial, anything after that one have to be sentenced by a judge/court and in this case the poor KLM pilot was deemed a flight risk if let loos, so he got 2 weeks behind bars just to make sure he would stay and await trial.
Not sure the above is draconian, he did not get caned or stoned, just got caught with his pants down.
(Note to self: Don’t drink and drive/fly in Norway. If you do, don’t get caught)
