There is so much petty crime that is no longer reported in France because people know the cops won't do anything about. What's the point of reporting it if you know that nothing will come out of it? I had my car broken into, my phone stolen on the train, I have been harassed on public transport. Guess how many times the perpetrators were fined/convicted? A big fat 0. And some of that stuff happened in areas with multiple "security" cameras who witnessed the whole thing.
