Alvin Townley wrote in "Legacy of Honor" about the large positive impact of Eagle Scouts in America. Townley cited such examples as how Scouts, especially Eagle Scouts, were disproportionately represented among Hurricane Katrina's volunteer relief workers; just as they are disproportionately represented among members of the United States Senate. Former Governor Rick Perry of Texas is an Eagle Scout who defended BSA policies and restrictions against ACLU criticisms in his book, "On My Honor: Why the American Values of the Boy Scouts Are Worth Fighting For".
