There's a concern the number of burglaries will increase once the new policy is in place.
The number of burglaries reported in Fontana in 2006 was 779, down from 782 in 2005, according to the FBI.
The Cal State study showed verified police response in Salt Lake City has resulted in a 90 percent reduction in the number of alarm calls answered by police officers.
The first full year in 2001, Salt Lake City saw a 1.8 percent burglary increase, the study showed. The following year there was a 12 percent increase in burglaries. In 2003, burglaries there decreased by 6.4 percent.
Fontana's police chief said the data his department reviewed didn't show that the city will become crime ridden. The department plans to review the policy in six months.
