They're extrememly dangerous, to America that is.
Enviros put these carnivores where they don't belong and then go about the process of bullying the surrounding communities off their property in order to give these animals "territory". All because suburban pipe-dreaming idiots and "backbackers" get all warm and fuzzy and decide to play God. Meanwhile the elitists among us are using them as a tool to further their agenda.
Most re-intoduced wolves aren't even the natural species. They're hybrids that lose their fear of humans during the "re-introduction" and other interaction.
They and other unatural predators (like the cross-bred inbred "Florida Panthers) are some of the most dangerous creatures on earth. I know this first hand.
My suggestion is if you see one these creatures anywhere near where you live, rid your area of them by any means necessary. Or suffer the consequences.
Those inbred Florida Panthers are doing a good job of killing themselves, whether through fighting or by getting hit by cars on the Tamiami Trail or Alligator Alley.
In all honesty, the most dangerous animal in Florida is the "endangered" American Crocodile. Currently, the tend to hang around the southern part (Flamingo) of Everglades National Park. I only hope that they don't reproduce enough to start moving elsewhere along the coast.
