I live in Florianopolis, the capital of one of the best state to live in Brazil (Santa Catarina). I have been robbed three times. Even people who have never been a victim will have the same feeling. Burglars are seen (and effectively are) potential murders. Every now and then someone is catch by security cameras being shot during an armed assault for meaningless reasons, such as the criminal not liking your face, not liking your possessions or discovering that you work for/is a policemen.
