I admit the video may serve to make some people think about knowing where the exits are and the need to escape, but in my opinion it's really more about pushing the dangerous mindset that says waiting for the authorities is the way to save your life. The video is a subtle indoctrination from the government that we should sit idly by and wait for "the state" to arrive and protect us, like good subjects.
If anything the video should make you think. You have to ask yourself, are you prepared to protect yourself if you were to find yourself in a life threatening situation? Are you willing to wait around and hope someone else comes to help you instead?
