There is a story in Texas that a Ranger asked a man, in broken Spanish, if he had a horse.  The man said no, and the Ranger shot him dead as a liar and a criminal.  It turns out that the man was innocent and had answered truthfully.  There is still bad feeling along the border about this incident.  In Spanish, there are two words;  the analogy that carries into English is asking a man if he has a bull, and then shooting him because he has a cow and answered "no."
