I think this would not be a good solution to crimes involving schools invasions. Improve safety by hiring professionals or investing in equipments that prevent the entry of malicious people,
maybe.
A teacher already receives a load of stress enough by the work itself, would not be fair or appropriate to make they get a training for this kind of thing, they did not study for it.
Even investing in security, schools, as well as all people living in a country where the crimes with guns are common and the ease of access to such equipment is clear, will not be saved this type of problem. I'm in favor of the legalization of firearms for citizens, since the government can not take care of the entire population, but do not like the idea of making the teacher do a job that is not his.
The problem is not to provide weapons to people who usually do not deal with this type of equipment, it would be easily solved with psychological tests and proper training and only those who are able to carry weapons, would carry them.
A plastic, wood and wire detector would be interesting as well as a safety inspection. I don't know, no one is completely safe nowadays, it's impossible.
