I don't believe that this practice would deter School violence in any way. It does no good for an officer to be carrying a concealed weapon if we all know he's carrying a concealed weapon. If I wanted to obtain a weapon that would be the first person I would Target. Also it would just make those Personnel the primary targets for any future School shooters. I think that we should do the research and look at how other countries are controlling these situations, and perhaps adopting some of their methods. They have already been the testing grounds for these sort of things and there's no reason why we can't use that information to make educated decisions on gun control or prevention of gun violence.
