Neighborhood Watch Program

A small suburb of a large metropolitan area has implemented a Neighborhood Watch Program. The town mayor has asked you to determine if the program is having any effect on the volume of complaints received about suspicious behavior, deviant behavior, and crime.

1. Is the newly enacted neighborhood watch program working to reduce crime?
2. How would you determine this?
3. Using what sources of information?

I need some help with starting this off and determining what sources of information helped determine this. Short answer is good.
