In more and more American churches there are parishioners in the pews with guns in their waistbands. I notice that several men in my church have taken to wearing large untucked aloha shirts. Someone bursting through the door with an AK will receive fire from several directions. Someone running down the aisle with a knife will not get much past the door. It also helps that the it is a tight congregation and strangers are noticed. Slipping quietly into a pew won’t prevent being taken note of.
I know some men in my church pack.
And I know they are real men who would lay their lives on the line to protect the rest of us.
No shooter would get far in our church.
