You have worked together with three other stock brokers in the same company for the past 12 years. The four of you are the best of friends, with strong personal ties going back 30 years; you grew up with these people, know their families, and go to the same elementary school and same church. Nevertheless, it is a surprise when one of the four reveals that he has been successfully trading on “tips” from an unmentioned source. You know that your friend has been having personal financial difficulties, but things seemed to be improving. Now you think you know why. Your friend invites you and the other members of the group to join in the trades based on the tips. You, too, face financial challenges as your children approach college age and apply to private schools with high price tags. Your parents are aging and face a deteriorating financialsituation. You have recently become concerned about dipping into your savings merely to meet monthly living expenses. One of your friends eagerly accepts the offer to trade based on the tips, but another argues that doing so may be against the law. She says that the trades are not worth the risk of getting caught, and she is in no way interested in hurting her family or career. You suspect that she might not participate in a cover-up if an investigation occurs. Your trader friend explains  his scheme. It seems foolproof, though perhaps of doubtful legality. The risks of getting caught appear minimal. What should you do?
