Guns in a school environment will only invite trouble

The argument

The case against arming teachers turns on what introducing a firearm into a school does to the environment as a whole, rather than on any single scenario in which one might be used. Proponents of this position point to the record of restriction: gun-related violence has decreased in K-12 schools covered by federal laws that restrict guns within 1,000 feet of school property, which they read as evidence that reducing the number of weapons present is what reduces the harm. Placing guns back inside the building reverses the measure that appears to have worked, and does so in the one setting where the population is least equipped to absorb a mistake. The scale of the background risk is what gives the objection its force: about 25,000 people die each year from firearms-related deaths in the United States, a figure that reflects the ordinary circulation of weapons rather than the exceptional event a school policy is meant to address. A second strand concerns competence. Teachers and students are not trained in law enforcement, and nothing in a teacher's preparation equips them to make the judgements an armed response demands: identifying a threat correctly under duress, distinguishing a target from a bystander in a crowded corridor, and deciding in seconds whether to fire at all. There is no way to prove in advance that any given teacher will handle such a situation the right way, and the consequences of handling it wrongly fall on children. Finally, a weapon kept in a school is a weapon that is not continuously controlled. Across thousands of classrooms and thousands of school days, there is a high probability that a gun will at some point end up in the wrong hands, whether taken, found or left accessible. That danger is present every day, not only on the rare day an armed teacher was supposed to be the answer.

Premises

Counter-arguments

Schools should have access to guns to be ready for any attack. Shooters are more likely to target a place if they know that no one will stop them. The weapon they carry will be no match for the absence of one. There is a need for a defense to stop active shootings, and relying on police officers may be too late.

Rejecting the premises

[Rejecting P1] A national annual firearms death figure, most of it unconnected to schools, does not bear on what happens when school staff are armed; and the fall in violence under gun-free-zone laws is reported with no comparison, so it does not establish that the laws caused it. [Rejecting P2] Lack of law-enforcement training is a serious objection, but the premise states it as a certainty — "no way to prove" and "high probability" are asserted with no evidence from the districts that have armed staff, which is where the answer would actually be found.
