My church in northern Virginia has had armed security detail and armed undercover protection for years along with armed county officers milling around between helping with traffic control. Sign of the times.
My church, in the Cincinnati area, has this. All attendees are welcome to conceal carry, as well.
I think 1/2 the guys and more than a few ladies at my church are probably packing heat. Anyone tries something like that, the worse danger might be from the cross-fire.
