It is stupid that they are putting any blame on the machine itself, spaldino, but I don't see how you could possibly think her not speaking english had anything to do with her being so absent-minded as to put a baby through the machine.
I mean, I don't mean to be critical, but, as far as I know, you don't speak Chinese, but if you were in a Chinese airport you wouldn't suddenly be stupid enough to put your kid through some conveyer machine where everyone else is putting baggage.
