During the age of sail, cannons could use cannonballs or grapeshot. Cannonballs damaged the hull, gun decks and masts, grapeshot killed people and had a larger damage area although each shot caused less damage. One has to choose the ammo depending on the target; the same is true when building cases in disciplinary and grievance hearings. Choose your [metaphoric] ammo with care and in the knowledge of the target i.e. discover the weaknesses in their case and make sure its on the table with the maximum of force, don’t get distracted by personal anger or irrelevant detail! Use a cannonball!
