I can assure all of you that the best way to extract information from an informant, while leaving as few marks as possible, is to judiciuosly beat the bastard about the shoulders and midsection with a 14 inch double headed black dildo. Men will cry like infants when struck with a rubber phallus, especially if you allude to its previous owner's foulness. Even if they aren't especially wounded by the proceedings, your ingenious use of a novelty item will leave psychological scars that will last for years, and make them think twice before trying to cross you in the future.
