I have a pitbull (American pitbull terrier) that is a rescue. He loves people, but is so aggressive towards other animals that I can hardly believe it.
After having one for years now, I believe there should be some sort of training or licensing requirement before someone can own one. The combination of innate aggression and power is truly dangerous
I can never walk my dog off-leash, I can never hand my dog to someone inexperienced. I love my dog, but responsible ownership is much more burdensome than any other dog I've had.
I don't think they would riot, they would probably just get pitbulls from breeders that didn't check for licenses.
But I agree with the gist, there are a lot of bad dog parents, and people get pitbulls for bad reasons. I want there to be an avenue to punish owners & breeders who do not take proper precautions.
