Why do American children die at such high rates?

From BBC News,

Why is the problem of violence against children so much more acute in the US than anywhere else in the industrialised world, asks Michael Petit, President of Every Child Matters. Over the past 10 years, more than 20,000 American children are believed to have been killed in their own homes by family members. That is nearly four times the number of US soldiers killed in Iraq and Afghanistan. The child maltreatment death rate in the US is triple Canada’s and 11 times that of Italy. Millions of children are reported as abused and neglected every year. Why is that?
