"...groundhog behaving oddly as if sick and/or rabid..."
I had to do this once. It wasn’t pleasant. The car we were driving behind plowed a deer and being a subcompact, demolished the car. The deer was thrashing around in the ditch, bloody mayhem. I took a shotgun we were transporting and put the poor thing out of its misery. I had forgotten about this incident until I read this article and was talking about it to my wife. The deputy showed up and I told him what I did and he said “good job.”
That said, it’s a groundhog people. We used to shoot them for sport on a sod farm when we lived back west (home). They sure do cause a lot of damage, let alone one rushing you. Never saw that before.
“In a sane world, decent men and women would humanely put down sick or injured wildlife without getting a dozen levels of official clearance to do so.”
Probably had to get permission to discharge his duty weapon. These days CYA is Job #1.
