I won’t tell you how I know but in our church any LEO in the church service have been asked to carry and any attendees who have concealed carry permits are asked to pack also. It’s a word of mouth thing, not announced from the pulpit.
This all began several years ago when a guy burst into a local church and held the congregation hostage over a domestic despute with his wife, a member of the congregation.
This wouldn't be the first time...
