Below is a disturbing video. Don't watch it unprepared.
It is of a man getting hit by a car in a hit and run. It is a horrible sight. That part is disturbing enough, but watch how no one bothers to help him. Cars drive by, people see him in the street, and no one goes to his aid. A news report I saw said that no one even called 911.
In case we begin to doubt St. Augustine's teaching of Original Sin . . .
