When you ask permission to photograph someone in the street the very concept of the photo changes. It ceases to be street photography and becomes a portrait.
What happens is that whoever takes photographs in the streets must be careful to follow certain ethical rules.
When a person is aware that he or she is being photographed, the magic of the moment is lost.
