I’m forwarding to you 2 articles on mass shootings/domestic terrorism: the first from STRATFOR, typically well done and highly critical of the Media with some suggested future responses which will never be considered. The second and OPED from the Washington Post that approaches the recent attacks from a totally different perspective- regrettably this approach too will get little traction from the Media or politicians.
