By the way, a pastor at a Catholic parish in Fort Worth recently told me that his parish is forming a “protection team” of retired police officers (i.e. people who have right to carry weapons that goes beyond the usual CCW laws - at least that’s how he explained it to me) who can be expected to be on church property on Sundays, feast days, at night during choir practices, CCD classes and so on. They’re think very proactively.
At my church we have several of those retired officers, armed, and in plain clothes. They sit in the back pews, all with the full knowledge and consent of the pastor.
My church is in Texas also.
