Do the benefits outweigh the risks?
Despite the widespread news coverage of mass shootings at schools, the reality is that school shootings are still a rare occurrence. In an FBI study of 160 active shooter incidents that FBI identified between 2000 and 2013, 27 – or about 17 percent – occurred at elementary, middle and high schools. Given that rarity, the challenges of effectively using a gun to neutralize a shooter without taking additional lives and added day-to-day risks, we argue that Trump’s proposal would not be effective in making schools safer overall for teachers or students.
It is difficult to address the question of whether, in the moment of a school shooting, the presence of an armed teacher is preferable to an unarmed one.
