Jerry_D, of course the parents did not sic their dog on the infant, but they had to know that full and mixed-breed pit bulls are extremely dangerous and have a well-justified reputation for attacking, mauling and killing infants and adults, un-expectantly and without warning.   They were irresponsible or negligent and should be held accountable for their actions. As I said in another comment, had Kamiko’s death resulted from her playing with a loaded pistol, the parents would have been arrested and charged with manslaughter or endangering the child, but since it involved a known dangerous dog breed, they are given a pass.  Why?
