That is a terrible experience you had in my country! I really feel sorry for you and your wife. I hope you both got over this experience and once will try to come in The Netherands again. It has beautiful things besides the big cities.
Once my mother's bag was almost stolen, in our village. So, it doesn't only happnes in the big cities. My mom held her bag tight. She was brave.
Once it alsmost happend to me too. I had my mother as an examnple and held my bag tight too. I called my father to pick me up from the station and that someone started following me. It was a creepy situation at almost mdnight when I was a teenager, coming back from violin lesson and orchestra rehearsal.
I also had neighbours where man broke in their house when they were asleep in their beds upstairs. That is just a creepy thought and experience.
These people have no sense of humanity.
I hope you get the strengths again and visit my beautiful country. Then, try to have walk through the forest or come visit small villages.
