Input: Consider Input: Question: What was the age difference between the commodore and his brother? Passage:Samuel Shaw was a Revolutionary War naval officer who, along with Richard Marven, were the first whistleblowers of the infant United States. As a whistleblower, Shaw was instrumental in the Continental Congress' passage of the first whistleblower protection law in the United States. Shaw, a midshipman, and Marven, a third lieutenant in the Continental Navy, were moved to act after witnessing the torture of British prisoners of war by Commodore Esek Hopkins, then Commander-in-Chief of the Continental Navy. Shaw and Marven were both from Rhode Island, as was Hopkins, whose brother was Stephen Hopkins, Governor of the new state, and a signatory to the Declaration of Independence. For reporting the misconduct of the Navy's highest officer, Shaw and Marven were both dismissed from the Navy. Worse still, Hopkins then filed a criminal libel suit against Shaw and Marven in the Rhode Island Courts.
