Some dogs are troublesome, and can be aggressive. All pit bulls are troublesome, and sooner or later they WILL be aggressive, wildly aggressive.
I don’t actually blame the dog. It’s a DNA thing, much like with a wolf it’s a DNA thing. This might excuse the dog. But in no way does it excuse the owner. You bring a wolf into a neighborhood, and you are sick trash. You bring a pit bull into a neighborhood, and you are sick trash.
Side story: I often walk a trail that winds past many houses. It’s a nice way to spend a day. Well, one of the home owners decided to buy a pit bull. It’s chained up in his back yard, and it lunges at anyone who walks by on the trail. That’s when I started to carry a revolver.
Wouldn't a shotgun be safer? With a revolver, you might only get one shot (and miss) before the pit bull is on you.
