Here's the picture for those who missed it.:
No, everyone does not know it.
Since everyone on this thread seems to think they are experts at reconstructing accidents by guessing, I'll throw in mine.
The jaywalker was drunk and ran into the car (passenger side) sideswiping it. I know that stretch of road, and it is dark at night. In this scenario, the Bishop would not have seen him, or necessarily known what happened. Other posters have already posted the story of a woman who almost ran the guy over too (head on) because it was so dark.
But rather than guess, why doesn't "everybody" just wait for the full set of facts?
P.S. Bishop Thomas O'Brien is not known to be a heavy drinker.
