Mary, a student at a community college in New York, is in the United States on a student visa that allows her to remain in the United States until she obtains her masters degree in biology. She is considering returning to her home country because she is concerned with the increase in crime at her college and in the surrounding area. Mary attempts to find information on the crime rates in her hometown to compare to those in the city where she currently attends college.

Why will it be difficult for Mary to compare the crime rates in a U.S. city with her hometown of London, England?

		England does not have any crime statistics that are available to civilians.
		There are differences in the way crime is measured.
		England is a dictatorship and manipulates crime rates so that their country appears to be safe.
		Only solved cases are included in Englands crime rates.
