Whoo, yeah. Several years after I retired we had a nutcase wannabe who was called the Freeway Sniper. He shot at cars and even a schoolbus on the beltway of Columbus, Ohio. He eventually managed to kill a woman after several failed shots at random vehicles. I got a call from Fred’s Boyish Incels. “Hi, we’re just checking in to see how you’re doing”. I knew why they had called. I told them no, it wasn’t me, guys, and it was not a trained sniper. The guy was missing baby crap shots from under 400 meters. He was caught about a week or so later. They keep you on their lists, alright.
Did you know they also monitor seismographs? Me again. The blaster for a local quarry had to have a gall bladder removed on an emergency basis. This put them behind as their backup was a rookie. So the boss asked me to help the rookie and offered a gee-whiz daily rate. Heck, yes! We were making excellent progress as I prefer larger charges spread out a little more. Soon enough, Al’s Tree Family showed up. The seismograph at Ohio State University noticed an increase in vibrations and triangulated the source. All was kosher. The rookie was licensed, just green, and I was not doing any actual blasting, I was just advising. Spooky that surveillance now extends to stone quarries by remote triangulation.
