Problem: Marcus is a witness in a civil suit for damages against Lindsay. Macy's department store is suing Lindsay for the alleged theft of a diamond necklace. Marcus takes an oath sworn by the court commissioner. He thereafter testifies that he saw Lindsay try on the necklace and then walk out of the store without paying for it. When the Macy's attorney asks Marcus what he was doing at Macy's, Marcus responds that he was buying some jewelry as a gift for his wife. In actuality, Marcus was shopping for jewelry as a gift for his girlfriend.
