Just got back from Home Depot. They have these new cameras at the self-checkout taking your picture. I asked about them and I was told IT IS THE LAW? They will loose their business license if they don't have them?

This was in Glendale, near where I live, but WTF? We can't ask people if they are illegal, but HD is snapping my pic all over the place for their records.

Is there some kind of new law?
