Wonder if whoever thought up this story has any idea what the mission of the U.S. Secret Service is?
From the Secret Service's web: "The mission of the United States Secret Service is to safeguard the nation's financial infrastructure and payment systems to preserve the integrity of the economy, and to protect national leaders, visiting heads of state and government, designated sites and National Special Security Events."
Which makes me wonder why they'd bother with this guy's stunt. If Apple wasn't happy with what he was doing, toss him out of their stores, end of story, I'd have thought. I bet he's hoping the whole thing goes viral, would get him more attention that he'd ever hoped for.
I kind of like the basic idea of capturing people's faces when they interact with computers, though.
