What a hideous cruel attack on Smokey! I hope that the law enforcement people & caring members of that community cooperate to track down whoever carried it out.
People who torture animals to such an extent are psychopathic...no empathy for the suffering of any other creature (human or animal), nor any remorse for having caused it. They are a danger to the community & need to be identified & watched very carefully.
I think there's one country where the law allows the animal welfare authorities to publish a list of the names of people who have been convicted in the courts of cruelty against animals.
In my own state here in Australia, a law has just been passed that allows the courts to ban people convicted of serious cruelty to animals from owning animals...for life. if necessary. The new law had been in place only 1 week when the court used it to ban an entire family from ever owning an animal again. They had a history of convictions for cruel neglect of pets.
