I would advise churches be on alert, too. And ushers, security packing heat. No, I’m not kidding. I sit near the choir loft most Sunday mornings with the music ensemble. Don’t think it hasn’t gone through my mind of that scenario. Person through the front door has a straight shot.
The man I teach Sunday School with does the same on an alternating basis.
You’re right. Any public gathering needs to be alert, and the people who run things like public water supplies, etc., had better be on the alert as well. These murdering thugs are used to having an unarmed populace to murder at will. When they don’t have it, who knows where they will start finding it. Schools would be my first guess.
Ditto! Have worked out several scenarios for that occurring, whether when ushering or in the pew.
