The website’s owner, retired police officer Greg Ellifritz, says, “People want to know what tactics and strategies will help them prevail should they be present during an active killer attack in a public place. I’ve been writing about the topic for almost two decades. Other folks have been studying the problem for even longer than that. I’ve written 400 articles about active killer attacks. I’ve linked to over 1000 more articles on the same topic written by other authors. This is a compilation of the best of all that writing.”
