I've said it before ,the wolves they brought in are not endangered, the original wolves are.And there are still a few in the lower 48. A group like this could become a non-profit and use that status to access the same funds to fight this. A suit stating these wolves are the greatest threat to the species that should be there would have to be looked at in the courts, but if we won the government could find it's self in the position of being required to remove these wolves to protect the genetics of the original species.
