Hi PEOM,
I don't have an answer but did want to comment.
I work in a church. Not security. And I worry about terrorist attacks most Sundays, especially on Christmas and Easter. In my state, GA, only LEOs and licensed Security Guards hired by the church can carry on the property. Fortunately, our legislator made it a minor misdemeanor offense. Not that I would EVER break the law.
I'm not privy to our church's plans, but I think since we hire 5 off duty uniformed LEOs for traffic control the church leadership is hoping they will be sufficient. Of course, if I were a terrorist and had properly cased the joint, I'd wait until all 5 were in our break room enjoying breakfast and take them out first.
So I'm interested in what your church formulates. Even might like to pass it on to my management.
Haven't watch BD yet but have it on DVR and will watch this week sometime.
