Today I saw and stopped a shoplifter in the center of Reykjavik. I stopped her just outside the store. Then I draw her back in to the shop. She was screaming. But then everything turned. People came to me and said, I was wrong. I should let her go and do nothing. Even the staff in the kiosk didn’t care at all, and came to me and said, that I shouldn’t care. Afterwards the girl was comforted by strangers and disappeared afterwards.

Is this normal? Can shoplifters just walk away free?
What do you do, when you see a shoplifter?
