I don't think there's a good enough reason for the gov to intentionally hit the alarms. I mean this sent a panic to everyone and people are pissed off. Also I can't imagine what would happen if an ACTUAL Ballistic Missile was sent to Hawaii and people don't take the alarm seriously bc of this accident. And I mean, similar things to this happen all the time. According to some article they were planning on doing a drill, some mistake probably occurred when they were conducting the drill, people are human. To me it just looks like a small mistake that may have caused big problems.
