In Dade County Florida, a nine month study in 11 neighborhoods showed a tremendous decrease in burglaries, robberies and thefts. This decrease was due to the use of cellular telephones by the neighborhood crime watch groups. 

Some Cellular phone companies are now donating or lending cellular phones to neighborhood crime watch groups.This is not only a good way to promote sales of the product, but a way to show what a valuable asset the phone can be in many situations.
