Good for you, man!
"Oh, my sweet little pit bull would never hurt anyone!" Or, "She is a loving dog, I can't believe she could have killed that little boy!" We hear it all the time. People get a dog bred for fighting and can't understand that a fighting dog would attack.
Many insurance companies either won't cover you or will charge a higher premium for liability if you own one of several breeds they believe are dangerous.
We've been watching the various animal shelters for a golden retriever. Every time we look, about 20% of the dogs are pit bulls. At least some pit bull owners figure it out. But management at the shelters haven't gotten it--they try real hard to place pit bulls in homes rather than kill them. Some day they will get it when one of their folks gets attacked.
Many years ago there was an article about 2 guys hunting birds, got charged by a bear. Both had pistols just in case. One had a .38 & the other a 9mm. Typical story, the bear died at their feet. Hit many times by both guns, only the .38 penetrated enough to have killed the bear. .380? Looks like it's good for pit bulls, but it might just make a bear mad.
