I would never dismiss the harm caused by religious or racial harassment. It's grim, dehumanizing and hurtful. It should be dealt with swiftly and thoroughly, as our legal system allows, to its credit.
However, it sure doesn't excuse murder.
If there was any group of Americans with grounds to snap at the hateful policies of the government and military, it would have been the Nisei living in the continental U.S. after Pearl Harbor. Rounded up en masse and sent into camps by Executive Order simply because they shared the same ancestry as one of our enemies, Japanese Americans had ample reason to be bitter and vengeful toward the country that turned on them.
Instead, they responded by volunteering to serve that country. The rest, as they say, is history--21 Medals of Honor worth.
Just something to ponder over the next few days.
