It's so easy to dismiss these notions out-of-hat because we're afraid to believe something so mundane could also be so tyrannical. But when you put these types of events into their proper historical context, as you have, you start to gain a much clearer picture into the realities of how the State can (and will) mitigate future incidents from happening.
