For more were joined by someone with a unique perspective on all of this, Ashley Nicholas is a combat veteran spending time in afghanistan. She also spent time after the service as a math and Science Teacher in san jose. Ashley joins us live via skype. You wrote for the piece in the new york times, much of what i learned in the army is horrifyingly relevant in the classroom. What do you mean by that . I think what i was trying to illustrate is that there was a striking similarity to a lot of the things that we did deployed in afghanistan to prepare ourselves for patrolling keep ourselves safe. I was able to compare those experiences the first him had to run to the drills with my students to show them how to be sheltered during an attack and start to think about the things i needed to do to prepare my classroom to withstand an attack. I think the reason that is so horrifyingly revant is the fact that our classrooms are nosigned to do that. Our teachers are not equipped to do that. It is not appropriate to ask them to. We need to get at the root of this problem and that his guns. Is not that our schools are not fortified. Talking about the classrooms, theres so much focus and trying to arm teachers, that is with the president s desk the president what others are saying. You said you armed your classroom to make it difficult for campus shooter. In a classroom that had large windows, two doorway so how did you harden the classroom without turning it into a fortress or prison. That is a difficult thing to do, which you harden your classroom to want to deter an attack if they come in without scaring your children or make it seem like you are fortifying in a way that is not appropriate. We did that by looking for ways to barricade the doors or cover the windows. What i want to emphasize is that is not an example. My classroom should not stand as an example of what should be done. We should not be looking for ways to do this effectively. We should look for ways to prevent the next attack, not defend against it. You talk about teachers having guns. The president talks about that. You would be a prime candidate for this kind of thing. Used to worry rifle with 30 rounds of ammunition, carried a nine millimeter handgun. You had a knife and body armor. You are totally prepared for this kind of a situation but i would imagine, dina and i percent of your fellow teachers are not trained like you are. What you think of the idea of your fellow teachers also carrying weapons . I think it is inappropriate. It would have been inappropriate for me to carry a weapon in a classroom even though i may have been prepared. The weapons you mentioned i carried in a combat zone where i was trained and equipped and prepared to defend against an attack. I took an oath and understood that was a risk. That is not something we should be asking teachers to do. We already expect a tremendous amount and burden them with a tremendous amount. To asked him to be willing to put their body in front of a bullet for their students is not something we should be considering. What do you think is the solution . This is the milliondollar question that nobody has an answer for. He will have complex solutions. There is incremental things we can do to expend background checks. One thing we need to focus on is finding a way to have it be meaningful and civil discussion. People purchase weapons differently. Those that have never experienced them talk about it one way in which i passed each other. We need to find a way to find Common Ground because well care about the same thing, keeping our kids safe.
