For your consideration:
Some time ago while developing our security ministry, I contacted the head of security at a large church in California to see if I could glean some wisdom from his experience. He recommended a great resource that they've used to educate, develop and fine tune their team. It's a book put out by the American Society for Industrial Security (asisonline.org) called “Crime Prevention for Houses of Worship” by Chester L. Quarles, CPP, and Paula L. Ratliff. It's an outstanding reference that's well worth the price. Its ISBN number is 1887056130. Here's a summary of the table of contents:
