Jaycee Dugard, who was kidnapped at age 11, released a public service announcement Friday.
The 20-second spot begins with a close-up of Dugard, then shows neighborhood scenes of families walking down tree-lined sidewalks.
An empty swing sways in a park as Dugard tells viewers to speak out if they see something amiss. She says, "You might be wrong, but you might just save someone's life."
The PSA ends with Dugard walking arm-in-arm with her mother, Terry Probyn.
The spot promotes the JAYC Foundation, which helps families get treatment following an abduction or other traumatic event. It can be viewed on the foundation's website.
