Hispanic-rights leaders say they’re targeting locals and tourists alike with a billboard warning of Arizona’s new immigration law.

The billboard cautions: “Have your papers ready – Racial profiling just ahead.”

The group behind the billboard in central Phoenix, at 3rd Street and Camelback Road, is Culver City, Calif.-based Brave New Foundation. The groups says it paid for the outdoor advertisement through donations to the Facebook page of a group called Cuéntame.

Cuéntame is an online immigration forum that has focused on Arizona’s new SB1070 law. Their Facebook page has over 38,000 “fans.”

Actor Martin Sheen speaks out on a Cuéntame video, calling SB1070 a “backward law”:

We cannot be silent as we see our friends and family live in fear and uncertainty, persecuted by leaders, who are using them as a tool for political purposes.

He asks people to sign Cuéntame’s petition, demanding Arizona lawmakers to overturn SB1070 and pledging to boycott the state.

Earlier this year, Brave New Foundation posted an online video in which a Phoenix police officer said the law would make him feel like a Nazi. Officer Paul Dobson was then placed under internal investigation and is expected to face some type of minor discipline.
