This is a difficult topic and so far a great failure of the United States. There have been too many school shootings here: if you search for “school shootings” and “stop OR prevent” in databases such as Academic OneFile, Education Research Complete, and PsycInfo, you will find that a good amount of research has been done. Perhaps a viable solution will be one that includes several different strategies, from better training and education to recognize those who may be in trouble, to better mental health services to help them, to better gun control laws, and so on (see this article and references in PolitiFact for a summary: bit.ly/stop-shootings). It will not be easy; educating ourselves (but beware of bots and trolls online) and talking is a good first step, but it does seem as though many lawmakers are not really willing to be part of the solution. We must keep talking and learning, speak out, vote for candidates who will address the issue. And we must continue to support those who have been victims of gun violence. Students in Parkland FL are leading the charge, with a planned march in DC (and one is apparently being planned here in Boston as well: bit.ly/marchforourlivesboston) as well as other events: bit.ly/walkout-shootings.
