Trump would go in ONLY if he had no other options to get clean toilet paper so he could clean himself up. More than likely though, he'd probably send in Eric or Jared first.
Trump, who dodged the vietnam draft and was spooked every time he has looked in danger, said he would go in 'without question'.
It's a tricky question. If I had no weapon and my daughter or niece was in the school, then yeah, I would go in, but without trying to confront the shooter, just trying to extract my daughter or niece and get out.
With a revolver, I would have felt I had to. I was speaking to my friend about this. A lone gunman with an automatic rifle, isn't going to be using marksmanship principles, he isn't going to be taking up positions, he is going to be presumably open, his stances are going to be too sh!t. He is going to be a predator without being used to moving targets etc. I think it is realistic that someone with, say a 9mm who knows what they are doing has maybe a 60% -70% of winning that encounter (remember the shooter still has better knowledge of the school, if Peterson is still too scared to go in). Not great odds, admittedly. If you are being deliberately cautious, then maybe 70% to 80%.
