I'm watching it now. One thing strikes me immediately - Jackson's initial body language (or lack thereof). His hands, with the exception of the times he is holding the Bible, are constantly kept under the table and out of sight. that's very atypical for a JW elder accustomed to make gestures while addressing others. Either was he tense of was coached to do so.
At around the 11:30 mark, Jackson reads from Acts 6:3, 4 and tries to imply that the Governing Body equates to the apostles and the 30 Governing Body helpers equate to the "seven reputable men". Angus then noted sharply that the text indicates that the "7 reputable men" were first selected by the congregation and only THEN appointed by the apostles, pointing out that the JW's have a different arrangement from the biblical example they profess to follow, since it's the Governing Body that selects and then appoints those helpers. Jackson failed to provide biblical argument to counter this, dismissing it as the interpretation of a secular commission.
