Great article. Nothing to add. My only tip:

I’m a State Licensed Armed Security Officer in uniform. I need to be very knowledgeable about what I say and how I act.

THE TIP: When I’m assigned a new location (religious or secular), one of the first thing I try to find out is where property lines and easements exist. Not every location has public sidewalks. It’s RARE anyone knows. If you don’t know about your church, try and find out, then write your Rules of Engagement Policy correctly.
