It can always go to that, due to nothing you’ve done.
Mistaken identity, planted evidence (from someone else, like drugs put in your bag by a handler for picking up by a compatriot in the destination, but caught before then, or by bored police!), political targeting (like you’re the ‘wrong’ nationality, and the country you’re traveling to wants some leverage), etc.
Muggers or bandits also don’t exactly ask if today is a good day either.
