From the Scout Handbook - "A Scout is loyal. A Scout is true to his family, friends, Scout leaders, school, and nation."
Loyalty means to be faithful. When we say a Scout is Loyal, it means he remains steadfast in his adherence to what is right. Being loyal is a character trait that can be often tested, and often misdirected.
When a friend of a Scout steals and then asks the Scout to keep it a secret to prove his loyalty, what should the Scout do? Is he being disloyal if he lets authorities know who stole? Similar dilemmas can occur when a Scout wants to be loyal to family or leaders.
If someone lies to protect another through a sense of loyalty, he smudges his own honor and he only prolongs the time until that other person gets into worse trouble. By being truthful, he may lose a friend, may lose love, and may lose popularity, but with his honor intact, he can live the Scout Law and know that, in the long run, he has done the right thing.
