Right after 9-11 I called the tipline they had set up.
There was a local KFC fast food joint that didn’t have the flag at half-mast. I went in to politely tell them. The place was empty, with three muslims working there - looked like a family.
“No work- rope no work!”
I went out to the flag pole and magically got it to work with no effort, and brought it down to half-mast. (Seeing I was on their property with a bunch of muslims looking out the window, I didn’t follow protocol by bringing it all the way down and back up again.) When I got home I called the tip number.
We had a few of them in my home town...and they’re in jail now.
