You have been promoted to the position of manager of your company's competitive intelligence organization

You have been promoted to the position of manager of your company's competitive intelligence organization. Senior management fired the previous manager because they felt he was too conservative in his approach to gathering information; they want someone who can "think outside the box." What ideas do you have about gathering competitive intelligence that would be effective, although perhaps somewhat unethical or illegal? Would you be willing to take these actions with senior management's encouragement?
