There is a line where, on one side, law enforcement is allowed to shoot at a moving car, and on the other side, they are not.
It seems to me (as a layman) that this incident is right on that line. There are forensics and legal experts who say it was a just shooting and others who say it wasn't.
I realize most people are going to default to their "team's" opinion on this, but when the people who are in the field can't agree, maybe this is truly an either/or situation.
