“The County of San Diego Department of Animal Services says within the past three years, both pit bulls have been impounded four times after being found running loose and returned to their owners every time”
There’s some ‘splaining to do.
...and some money to pay.
I expect the explanation is that the pit bull owner had the right connections. Notice that the story names everyone except the owners. Even the reporters are afraid to name names. Expect the story (and the criminal charges) to quietly go away.
