So Pennsylvania's code, read one way, suggests it is and Florida's says it isn't.
Ethel is right! The version that clearly says it isn't accords with English law and the legal principles of the common law (fundamental to law in the US)
I can't see that 'death dangerous' is a crime of moral turpitude in English law. We don't use the term 'moral turpitude' but it translates into what we would term 'malice' or 'dishonesty'. Recklessness is not 'moral turpitude'.It's not even an essential element of the offence. You are guilty of the offence if 1) the way you drive falls far below what would be expected of a competent and careful driver and 2) it would be obvious to a competent and careful driver that driving in that way would be dangerous and 3)death results.You can be doing your incompetent best, for example, as a new driver who hits the wrong pedal , completely misjudges the speed of an oncoming vehicle or fails to see an obvious pedestrian.. The 'mens rea' (the mental element) in such a case is non-existent.It may be that the driver sets out to drive dangerously, but it in most cases they don't.(If a driver is deliberately setting out on a life threatening way of driving, and someone is killed, that's manslaughter, not death dangerous!)
