Not only that, but it appears (emphasis on that word, please) that the jurors in the portion you cited thought the agents were guilty, but disagreed with the length of the sentence. Do jurors know the length of the sentence when deliberating? Honest question.
I don't think so. They obviously did not in this case.
If I remember correctly, jurors are not told the potential length of sentences while deliberating for the same reason they are not told of prior criminal acts by defendants. It might prejudice them.
