The P&E continues to understand the Tennessee law
At the state’s convenience, the grand jury foreman has been referred to both as a juror and as an administrator. State law describes a grand jury as consisting of 13 randomly-selected citizens of the county who are eligible to serve.
He is both a member of the Grand Jury and an administrator but unlike the other 12 jurors, he is appointed by the Judge from the general public. This is not rocket science and the supporting facts are quite self evident. With this kind of argument, poor Walt will spend more time in prison. One would at least hope that his friends would correctly inform him of the facts.
