As society advances, many kinds of crimes have been increasing day by day. They can takeplace in any city and penetrate every corner of society. The most common crimes directly threateningpeople are burglary and street crime. But crimes vary in different cities, and in different countries. Insome big cities of America, street crime is a constant threat to society, while in our country, burglaryis usually a big problem. These kinds of crimes and the fear they cause are changing the fabric ofsociety and forcing its citizens to change their traditional patterns. In some cities of America, no onedares to leave home at night; no one feels secure even in his or her own neighborhood.
