Three boys were leaving Wal-Mart when they were stopped by plain clothes security officers. One officer said, "Those shirts that you have on were stolen.” One boy said, "You can't be serious". The officer responded, "Yes, I am. Come with me". The boys then went with the officers to a side door and into an office. The boys' parents have filed suit against Wal- Mart. Discuss what their suit might be for and what defenses Wal-Mart has.
