There were 20 of them, cute and innocent as could be. The farmer raised his shotgun and pumped one shot after another into each one of them, killing every last piglet, and their mothers too. This was heart-wrenching for the farmer, but he knew he had no choice since the State of Michigan was about to descend upon him with a SWAT-style team intending to arrest him as a felon if any of his pigs were found alive on his property. His crime? Harboring an animal that the State had designated as an “invasive species”. And this farmer’s tragedy was not the only one to play out in the State; there were thousands of others facing similar dilemmas.
