"We can either react like some of our Fore Fathers did and start up the prison camps (Japanese Americans), take away their rights and debase ourselves..."
When my father was a small child, my grandparents lived in Daytona Beach. During WWII, they had black outs to prevent the Submarines offshore from sighting the tankers and freighters traveling up and down the coast. The Japanese were not as big of an issue as the Germans were in that time and place. Many Germans were also placed into internment camps, however, there was a wealthy grove owner that was German and he was left alone due to his status. He was an upstanding member of the local community and attended church regularly with many of the local politicians. He was also a family friend and he used to take my dad for "horsey rides" by bouncing him on his knee.
One day this fine upstanding pillar of the community disappeared. After the local authorities searched for him, they located a short wave transmitter in one of his pump houses in his grove. He was a spy. He sent info to the German subs off the coast regarding the ships he sighted traveling off the coast and many were destroyed resulting in loss of life and cargo. There was evidence of an inflatable raft found later which he used to row out to a sub to repatriate to Germany.
So, I have no idea how to determine where somebody's loyalty lies, but my family taught me a good lesson. You can't judge a book by it's cover and you can't trust your enemy. No matter how nice they are.
