If you want to record the meeting just fess up right at the start that you are recording and will be happy to provide the committee with a copy if they request one.
Don't negotiate the point, you are recording and that's that. Just remind them that if they choose to terminate the meeting you will expect no action to be taken against you.
If you refuse to stop taping and terminate the JC you will be deemed unrepentant and disfellowshipped in your absence.
if it gets as far as the JC and you don't want to be DF'd then, barring any procedural errors, your only way is to plead repentance and then fade away.
