Several police officers search a house for an armed suspect.
The area of Rochester, New York, USA, where these pictures were taken is part of the so-called 'Crescent', a moon-shaped area that runs across several city neighborhoods. Crime rates here are significantly higher than the rest of Rochester. The Crescent is home to 27 percent of the city's residents and 80 percent of the city's homicides. The causes of the burst of violence include the lagging upstate economy, a steady migration of residents to the suburbs, and a growing number of abandoned houses prone to become centers of drug sales and use. Rochester also has a school system that performs poorly. People inside the Crescent experience those problems in greater concentration.
