Somebody *Did* Get Unjustly Fired in Hawaii, But System Problems Should be Blamed

TL;DR Summary: "Employee 1" (the guy who pushed the "wrong" button) got fired. But the FCC report says: "The report finds that the false alert was not the result of a worker choosing the wrong alert by accident from a drop-down menu, but rather because the worker misunderstood a drill as a true emergency. The drill incorrectly included the language "This is not a drill."  So, the language from the drill didn't meet the standard for what the drill language is supposed to say. So, how is it fair to fire the worker who heard "this is not a drill?"
