It's not exactly a secret that street crime is an issue in Brazil (enjoy the World Cup!). For instance, take this video, in which a woman's necklace is ripped off her body while she gives an interview to a Rio news program about the epidemic of people being robbed on the street.
The reporter, bless him, chases after the young boy, who is eventually apprehended by police. The woman seems to have an okay sense of humor about it, and appears to have retained at least a part of her necklace.
Sometimes life imitates the art that is local television news.
