Not to pile on - here’s one of the pig farmers testifying before the Michigan Senate Agriculture committee. You are giving the DRN way too much credit. This is long but worth the watch.

Don’t you just love it that they don’t indemnify the farmer if the DNR comes in and kills his pigs? “We only indemnify for livestock. Once [Director Stokes] declared these as in invasive species — sorry, we don’t indemnify for invasive species.” All because someone decided that the standard meaning of “feral” could be played with at whim in order to wipe out the small competitors of, as Velociman put it, “Big Pig.”
I know how people want to run away from arguments that sound slippery slope like, but come on folks. How many once slipper slope arguments that are now tumbling down the hill do you need to have lived to have seen before you figure out how powermad our tyranny has become? Thus: give the govt bureaucrats power to define AT WILL like this, and tomorrow YOU could be declared something subhuman that would allow them to eliminate you.
