If we didn't have this authority, an immigration officer who would determine that they had found someone who was working illegally and subject to removal, knowing that the person would be a flight risk, would then have to leave that person, go and get a removal order, and then come back and try to find the person who, by that point, if they are a flight risk, would have disappeared.
Si nous n'avions pas ce pouvoir, un agent d'immigration qui constate que quelqu'un a travaillé illégalement et doit être renvoyé devrait, en sachant que l'intéressé risque de prendre la fuite, laisser partir cette personne, aller obtenir une mesure de renvoi et revenir pour essayer de trouver la personne en question qui aura probablement disparu.
