When there's crime where you live, your local neighborhood watch may already be on the streets, watching for suspicious activity and reporting them to authorities. But that's old school.

A growing number of your neighbors are going online, and using social media sites to report anything unusual. Plus, local police departments are using that data, too, to improve their patrols and outreach efforts.

Officer Quinn Fenwick, assistant police chief for Ventura joins the show to discuss how his team has used sites like Facebook and, more recently, NextDoor.

We'll also hear from Darryl Ospring, who uses online networks to help patrol her neighborhood of Coyote Creek in San Jose.
