"Hasn't it?" queried Kingman. "My worthy opponent, all questions have an answer."
"Objection overruled," snapped Hamilton sourly. "Let the witness answer."
"It is impossible to send communications without sending some energy. It is the intent to which the energy is put that determines the classification."
"Explain further."
