By rehabbing they point out the responsibilities in owning one. It’s pretty clear that as a humane society they deplore irresponsible ownership. I’m not sure if they approve of government restrictions, but they are always there when animals need to be taken from owners, no matter how badly the animal was treated.
If the behavior of irresponsible owners in not modified, the Pit Bull situation, and the calls for banning and severe restrictions, will continue to increase. That group does not address that point directly, no matter how much good they’re doing in other areas.
