Breaking Point

Your were thinking it! 
Unfortunately, the tendency for most organizations, especially well established, traditional, community groups that meet for generally "good" purposes, is to count on "what everybody else has" as the standard, and that that standard is sufficient. 

"if it's not broken, why fix it?" Or, "it's worked for us so far". These are common statements and thoughts made throughout nearly every industry and service that has never experienced a serious incident. 

Everyone Googles  everything today, so try this search: Lessons Learned from church shootings. 

My personal and professional experience, over 28 years in law enforcement (patrol-streetwork), and several years post-retirement working as an emergency preparedness Subject Matter Expert (SME) contractor for the federal government in the legislative branch and at the executive branch service level has given me a unique perspective on not only the methods, processes, and programs that have been tested and tried (literally by fire), but also the front-line, ready-for-anything attitude towards emergency preparedness. 

The safest and most effective approach to keeping your community and membership safe is to prepare, evaluate, improve, repeat. 

Questions to ask yourself:
If X number of my membership CARRY the TOOLS necessary to stop a violent problem, where (within the physical space they occupy at the time) will they engage the problem FROM? 
Have we practiced our plan lately (or at all)? 
Does everyone know the signal for "get down!"?
When was the last time the "ready" members conducted a proficiency evaluation? 

Your answers will probably make you a little uncomfortable. If so, your next step is to contact me.
