Witness

An interesting word than can be a noun (gerund) or verb. She says you think that none of the police . could tell a crook from a bag of elbows. This sentence doesn't make much sense. A "crook" is a good word . for a thief or other person who makes a living by dishonest means, and "elbows" are the joints which allow the arm to bend. Good appetite! ................
