The sites of many other mass shootings (Columbine, Virginia Tech) were not gun-free zones and yet many still lost their lives. The presence of more guns does not discourage mass shooters and does not prevent more violence. We can also see that training and experience with a weapon does not necessarily mean those trained individuals will act with good judgement (e.i. hundreds of instances of police shooting unarmed individuals). Arming people in schools will ultimately not reduce the risk of school violence and will increase the risk of gun related violence due to accidents or poor judgement.
