What if Flynn took the guilty charge knowing that in doing so would expose the DS and bring down the house of cards? Do you think he would take that chance? Would there be a plan in place, planned out and all paced out to give all the players involved enough information and rope to hang themselves publically and behind closed doors making statements that they never thought would be made public?
Something happened. Allowing DS to either give us more info or hang themselves more. I think Flynn being echonerated will be the first step in a chain of collapse of their plan.
