Are you seriously blaming the police for the death of that? Surely it is the guy's fault for stealing a car with a child in it and recklessly driving it.
"Blame" might be too far but there's definitely an argument to suggest they caused the baby's death, in that if they hadn't chased then maybe he wouldn't have driven so recklessly. Hence this whole discussion.
"Experts say there are few national figures on police pursuits. National Highway Traffic Safety Administration figures, based on reports from police departments, show that 305 people died in pursuits in 1991.
Of these deaths, 250 were reported to be occupants of fleeing vehicles, 46 were third-party victims in uninvolved vehicles, four were occupants of police vehicles and five were pedestrians."
Unless pursuit deaths rose a magnitude plus, I think you are misrepresenting some facts.
