And I'm sure they'll continue to believe that right up to the hour when an ISIS murderer blows away a classroom full of people.
I had the impression that in the USA at least, classrooms full of people are generally blown away by disgruntled former students and other natives without connections to ISIS.
Here are some of the facts.
The serious point, though, is that arming teachers and professors is a suggestion that, at the moment, is simply outside the ambits of rational discourse and political possibility in many countries outside the USA. Contrary to your apparent belief, this isn't because everyone else is naive, stupid or has a poor war record. The USA differs from my country (Australia) and many others in its "gun culture", which I take to include attitudes to and public discourse about guns, their accessibility, the extent of gun ownership, the uses to which guns are actually put, and regulation and the politics around these things. And this is not one of the aspects of american life which we envy. In this area (certainly not in all), we pretty much unanimously prefer to be the way we are rather than the way you are - one outcome of the way we are being a much lower incidence of all kinds of gun violence including classroom shootings.
Now of course, we could change our minds about all this. Over the next ten years we are likely, or IMO certain, to come under domestic attack by terrorists using guns and other weapons and it is perfectly possible that our disgruntled former students may imitate some of yours in turning to violence. When these things happen, we may decide that part of the solution is arming our teachers. In making that decision, we will look closely at the USA example and will find it interesting if there turns out to be evidence that your different approach to guns has protected you against gun violence inflicted on innocents in classrooms, as some of you apparently believe to be the case now.
