An old man told me, when I was quite young, the best way to train a dog is being smarter than the dog. Apparently a multitude of dog owners are not.
It's ok if you disagree with me. I can't force you to be right.
I do think that this is a problem. I have handled a few of these cases and the injuries are vicious. I know that some cities used to regulate them.

Recently, the Ontario Humane Society and OSPCA (Ontario Society for the Prevention of Cruelty to Animals) both announced they would no longer euthanize pit bulls or dogs involved in attacks. Both are required by law in Ontario. The exception to their new policy is if a vet looks at the dog and says they need to be euthanized. But I guess the OSPCA recently took in pit bulls that had been trained in a dogfighting ring and given steroids and crap and they opted to have them rehabilitated rather than euthanize them. Interesting.
I always agreed with the government about the pit bull ban until fairly recently, but I am not sure whether I agree with the dog attack part of this change in policy. I think that a lot of dog bites are accidents often caused by situations beyond the dog's control. But that is not always the case...
Your not just talking about training, you are talking about genetic characteristics. Even if pits attacked at the same rate as other dogs they would do more damage because they have a tendency to not stop the attack.
You can probably make a duck dog out of a Collie but it won't be the equal of a Lab or retriever due to genetics.
In the same way a pit or rot is a bad idea for a family pet.
