Armed Guard

The president's anguish over this latest campus massacre is no doubt genuine. We share his grief. He says grief is not enough, that we have to do something.
Why not tell us what to do Mr President? What bill do you offer, what legislative scheme? Will you rally the governors you cited? Tell us how to stop this in the real world, with implementable steps that do not require some vast left wing conspiracy.
You blame the gun lobby? Why not take them on? Confront the NRA and call out every hack who ever took money from them. 
By all means do these things.
But until the coming of utopia, advise every educational institution of a certain size to have one armed guard on premises to fight fire with fire.
