The press don't go around surreptitiously recording people.

If the kid had started off the conversation by saying "I'm going to record this", then he would have been fine (legally speaking; the principle probably wouldn't be happy and likely wouldn't agree to it). Being informed that a conversation is going to be recorded and then proceeding with that conversation is granting implicit consent to the recording. The problem is he recorded it in secret, which means there was no consent.

In the case of journalists, when a journalist thrusts a tape recorder in your face and asks you something, it's pretty obvious it's being recorded, so answering the question is giving consent to the recording.
