A hung jury is no verdict at all. Its just means another trial with a new jury until a verdict is reached.
Luigi will be paraded in his jumpsuit until he is formally jailed or dies. Anything else requires everybody to agree on Not Guilty, and that’s astronomically unlikely given the volume of lobbying against him.
Whether or not he did it isn’t even relevant anymore. It’s whether the common folk of a jury think he did, and both supporters and detractors of ‘The Adjustor’ consider that to be Luigi. His identity is so entangled in the public consciousness that the only way out is nullification, and prosecution is unlikely to allow such a jury to form.
Hung jury =/= jury nullification.
