Shoot the pit bull owners they make the dog mean.
When my elderly mom was still independent and living in her own house, she owned two pit bull terriers.
She loved those dogs like her own babies from the time they were pups, but let me tell you. Those dogs were absolutely vicious, and would likely have killed anyone they came in contact with, other than my mom.
Visiting her was a nerve wracking experience. The entire time we were there, her dogs were trying to break through the doors and windows.
It's not the owners. It's the genes.
