It could happen, though, that you would have an undercover situation, as you've already described, where adult A is talking to someone, to adult B, about finding and having an opportunity to sexually abuse a child, and adult A doesn't know that adult B is an undercover officer.
Il pourrait arriver, cependant, comme vous l'avez déjà mentionné, qu'un adulte demande à un autre adulte de lui trouver un enfant dans le but de l'agresser sexuellement, et que le premier ignore que le deuxième est un agent d'infiltration.
