That's why the sentences will run concurrently, but I don't understand why people think this is a big deal. Just had a women on drugs hit and kill a motorcyclist. She's charged with speeding, reckless driving, OUI, leaving the scene and vehicular homicide. All from the same incident. If, for some reason, the jury finds that she wasn't impaired, that doesn't mean she didn't speed.
Just as if the jury found that Chauvin wasn't guilty of second degree, he may still be guilty of third degree. As Woz pointed out, prosecutors may be reluctant to have lesser includeds presented because of the risk the jury will opt for a compromise, but there's zero wrong with doing so.
