It is absolutely true so do not state "that is simply not true"
But you are correct that an innocent mistake, for example biking near the Dutch/Belgium or Swiss/German border would not lead to an arrest. I am referring to getting caught on a bus, train or car deliberately attempting to cross the border, for example between France and Spain or Austria and Hungary, with no ID.
