Gun nuts are scared they might lose some of their "rights", so Donald Trump has to say some thing to make everyone forget the real issue. While the NRA says only a "good guy with a gun" can stop a villain, the lone police officer stationed at the school failed to do anything which proves that this theory doesn't meet reality. While I can't exactly blame him for being scared (horribly outmatched in firepower there), the officer did become a coward in that situation. However Donald Trump, as smug as he is, says he would have taken someone like Cruz down even if he was unarmed. Really Cadet Bone Spurs? I'd imagine you would have run chicken down to the nearest McDonald's.
