Their tears mean nothing. Those soldiers were traitors to the United States of America. They fixed bayonets and used weapons of war against the people of the United States (treason). They didn't make good on the oath they solemnly swore to uphold. They violated the Fifth Amendment to our Constitution.
They used armed military force to round up 70,000 American citizen men, women, and children and transport them to concentration camps without any individualized suspicion or due process of law.
Their tears mean absolutely nothing and their unprofessionalism and lack of concern for the very first duty of military service, to support and defend the Constitution of the United States against all enemies foreign and domestic, is no excuse. They finally knew? After taking the most solemn oath to support and defend the Constitution and then thinking nothing about reading or knowing or caring about it? There is no excuse for that at all.
Don't be like them. Because you will find yourself in a situation like they did, or worse. Count on it.
It's worse today than it was then, and in my experience our military folks have learned absolutely nothing since 1942.
