School Shootings and Gun Violence Exist. What Can We Do?

It goes without saying that school shootings are terrible. Something needs to be done, but what can be done successfully? Guns have been incorporated into the lives of Americans via hunting and they can obtain guns legally. Is it fair to ban guns entirely for the rabid school shooter? There are precautions set up with these things, but they aren't working well enough. Better equipping schools for the chance of a shooting would be a good move but is there something that we can all do? In times like these, we should just support one another and grit our teeth. Love to you all.
