Fake news. The car had three bullet holes in the windshield and one that we can see out the rear side window. The car wasn’t hit with a machine gun. The side door was opened suggesting someone was taken out through that side door.
The Iranian first responders themselves would have opened that door to get to and remove the dead and injured so an open door means nothing.... though I think an extraction would be desirable in order to get information from him in order to plan future strikes. Then again, the Israelis already acquired the mother load of information in the warehouse raid a while back.
