I am wondering if it is possible to make a customs officer check your bags for e.g. drugs before you actually go through customs?
Because let's say I am coming with a flight from Amsterdam, where Marihuana is legal. Of course I checked my bags very carefully, but in some countries (for example Singapore) even a tiny amount can bring you in huge trouble. Therefore I am wondering if it would be possible to go before actually going through customs and risking being stopped and checked, maybe with a dog who than smells something and somewhere in the corner of your bag a seed is found, going to a custom officer and tell him your situation, who than checks your bag and if something is found you tell him that you of course did not want to bring that into the country?
I want to make clear that this question is hypothetically and of course sounds kind of stupid, but I am just wondering if that would be possible/legal?
I am looking forward to hear your constructive thoughts!
