The more I watch it, they did turn pretty fast (forget my old grandma comment), but there is no way in hell they should have ever attempted that turn, even if the cop was going 45mph. They started their turn when he was like 100-150 feet away. They got hit about 1 second after they turned and at 94mph, that's about 140ish fps. Cop is still wrong though, but I think that living with their death on his conscious is punishment enough.
