You will be favourable to Burr, and so must fail because the American reader cannot bear a surprise. He knows that this is the greatest country on earth, Washington the greatest man that ever lived, Burr the wickedest, and evidence to the contrary is not admissible. That means no inconvenient facts, no new information. If you really want the reader's attention, you must flatter him. Make his prejudices your own. Tell him things he already knows. He will love your soundness.
