Um, okay, I think the police officers and that couple are all stupid.

It's a dog in a car --- you should expect it to protect it's property! Leather would have been put down a million times for lunging at people from the car. Someone was even stupid enough to put her face up to Leather, who was barking and growling like crazy. Well, she got attacked on the face.

The couple was stupid for not even caring about their dog. They are obviously not very attentive. They didn't even stop fighting. I hope that dog finds new owners who will take care of him and love him more.
