Tourists in Barcelona are increasingly taking extreme precautions against rising petty crime, highlighted by incidents like Sir Ben Ainslie's robbery at knife-point for his Rolex watch. In 2023, Barcelona saw an 8.6% increase in crime, with thefts accounting for nearly half of this rise. Locals advise visitors to keep valuables out of sight and avoid quiet alleys to reduce the risk of theft. Meanwhile, Skid Row in Los Angeles is notorious for its extreme poverty and violence, as revealed by a YouTube creator's experience documenting the dire conditions faced by its homeless population. Cities like St. Louis, Detroit, and Baltimore also struggle with high violent crime rates, influenced by socioeconomic factors and public perception of safety. Internationally, cities such as Caracas and Johannesburg are plagued by violent crimes linked to economic instability and inequality.
