I'm not sure if McHenry County is officially a 2A sanctuary or not, but that's a heavy response just for ammo. Several years ago, the McHenry County SWAT was at my neighbor's house in full gear looking for a felonious family fugitive. Scared the bejeezus out of my wife when she was on the front porch enjoying a morning breath of fresh air and they came walking around the house. There was no call for a shelter-in-place order then, and the town PD didn't even know it was happening until it was over.
I assume that they executed a search warrant to find something else, but then arrested the guy to make him sweat and snitch on someone. The article said the arrestee had no prior criminal record in McHenry County, but not if he had no record whatsoever.
