Getting out of the car to confront them is one thing. What this guy did is another.
He possibly didn't have the actual culprit
He doesn't have any evidence anyway
He left himself open to other accusations
If he had injured the child, guilty or innocent he would have been in trouble.
I know how annoying this is, having experience of it in cars, and in lorries
All you can really do is inform the police that it's going on in whatever area. This has gone on for years on end.
