Your are just ignoring the fact that pitbulls are just more efficient in killing than any other race. Even if they got replaced, it would result in less deaths because not a single breed compares to them in terms of killing.
So yes, pitbulls are assault rifles, German Shepards are 38 revolvers and your friends Cocker are butter knifes. Changing one to another is safer to everyone
Tell me when a cocker reach this kind of mortality then I will tell you to ban them too 
Don’t create excuses. Not all dogs are the same, this dog is a murder machine and should be put down. It’s not their fault, but this doesn’t change the fact that they were bred to maximum damage
My thoughts are just based in numbers, yours, not so much
Except this breed was created by us specifically for its violence. It’s in their genes. As far as I know there was no artificial breeding for pure violent humans. We created this abomination, we should put and end to it
No, the second best was 10 years minus 1 day ago
Cute, but should be put down as all others of this race
Of course it solves, for the people and other dogs who would get bitten by them
