“The Letter” Yоu аre wоrking midnights аs а pоlice officer and are on routine patrol within your sector/beat. As you are driving the vehicle in front of you swerves to miss a deer crossing the road. The vehicle then goes off the roadway before striking a tree. You immediately stop the cruiser and call for Fire/Rescue. You walk up to the vehicle and observe an unconscious male occupant. You remain calm and wait for Fire/Rescue. You are trained not to move an individual to avoid further serious injury. As you are waiting for Fire/Rescue the unknown man slowly regains consciousness. You tell him to relax and remain still because help is on the way. All of a sudden, the vehicle catches fire. You quickly remove the man from the vehicle and drag him next to your cruiser. Less than three minutes later the fire spreads throughout the vehicle. The entire vehicle is engulfed in flames by the time Fire/Rescue arrives on the scene. The man is transported to a local hospital with serious, but non-life-threatening injuries. You arrive at the hospital in order to complete the accident report and obtain the driver’s identification. As you are asking the driver for his name, address, and other usual information, the man then pulls a $100-dollar bill along with his driver’s license out of his wallet. The man later identified as, 78-year-old Jack Goldberg says, “Officer, I only have a $100 dollar bill on me, but take it. You saved my life and you do not get paid enough for what you do every single day.” You quickly say, “Thank-you for the offer, Mr. Goldberg, but I cannot take money. This is part of my job.” You then complete the accident report. Jack Goldberg was extremely appreciative of your actions and continued to assist you take something in return. You finally advise Jack Goldberg to get well soon and make sure to notify his car insurance company of the accident. You provide Jack Goldberg with the accident report number, your business card, and leave the hospital. Two weeks later you receive a letter in the mail from Jack Goldberg. The letter is addressed to you and your supervisor gives you the mail in roll call. You open the letter and Jack Goldberg writes you a very professional and respectful thank-you letter. Jack Goldberg also called the Captain, Allison Jones to advise her of your heroic actions. However, the letter also had three crisp $100 dollar bills inside. The note read, “Officer, I told you I insisted on giving you a thank-you the only way I know how. Please take this as a token of my gratitude.” Ethically, how do you handle the situation? What should you do in this situation? How would you react to receiving the gift? What additional options are available in this situation? What ethical system would you use to guide your decision-making in this case? Why? Please remember to be as detailed as possible and answer the scenario-based question in 3-4 paragraphs (4-6 sentences per paragraph).
