Agreed MarcK - the first guy in to help walks round for roughly a minute, probably wondering what to do, then suddenly sees something. As he rushes in, the guy who moved his car (and had just hung up his phone after presumably calling 911) goes right after him to help.
I'm thinking I would have called 911 before (or maybe while) I moved my car, but I don't see much to criticize in the bystanders actions.
