U.S. v. Villasenor (9th Cir. - June 10, 2010)

A car drives through the Calexico border station. It gets inspected at primary inspection. It get referred to secondary inspection. It gets dog-sniffed. Clean. It leaves.

The car then heads north. The driver stops at a gas station, and talks on his cell phone for ten minutes, and goes to the restroom.

The driver then drives a couple of miles and goes to an AM/PM. He talks on his cell phone for five more minutes. He then drives on.

He drives for another half hour. Now he's in El Centro. He drives to the DMV, and walks in. He does his business there, and then drives off some minutes later.

Shortly after the driver leaves the DMV, he's pulled over by the cops. Sure, the dude's far from the border with Mexico at this point, and has done a plethora of things.

But the Ninth Circuit holds that this is a "extended border" stop. Hence okay.

Remember that the next time you're anywhere near a border. Like, say, if you live and spent nearly every waking hour there.
