The shooting at Marjory Stoneman Douglas High School was a tragedy. With each new bit of evidence that comes to light about the shooter, it becomes more and more evident it is a tragedy that could have been prevented. The ball was dropped not once but a number of times. Amid the calls for stricter gun control laws came the renewed suggestion that it might just be time to arm our teachers and administrators. Oh, the howls of outrage and misinformation that immediately followed President Trump’s comments on the matter. You would have thought the President and those supporting his suggestion were advocating every teacher coming to school in MARPAT with AR-15s strapped to their backs, guns at their hips and combat knives to their legs.
