You need to understand the difference between 'working for' and prioritising.
Even if jb had x amount of people in his legal team this doesn't mean that he is the number one priority for any of these who will have different priorities.
Surely u don't think Simon McKay et al work 24:7 for jb?! People spend far more time on this forum debating jb than his legal team spend 'working' for him.
Anyone working full time for Bamber must have
1. A lot of time on their hands.
2. Nothing better to do, because surely there are easier ways to earn a crust.
3. A blind spot in their mind if they are willing to work full time at a case where other capable people have strongly failed to win an appeal.
