It would have depended what was in those documents ?
When my bro.was on business,he invariably and surreptitiously had his briefcase handcuffed to his wrist,and always kept a " note " on his person that in case of an accident the police were to take that briefcase,etc etc. if he wasn't able to hand it in to the nearest police station himself.
I always remember years ago wanting to visit Russia to see the beautiful architecture,but bro. had said " I'd rather you didn't go ",but didn't say any more ?
