Why did B.O kiss Calderon's corrupt ring today?

He basically let an invited guest to his home slam his family, and agreed with him to boot! Mexico is a cesspool of corruption, all the way up to Calderon, but B.O didn't get the memo. He instead slammed Arizona again, for a law that neither he, nor his Attorney General read. Perhaps the only thing B.O can read is a telepromter? Ooh! I know my next question!
