It is true that JW's always have a answer about an issue. No matter how much you try to entrap one in a argument they will quote a scripture supporting thier viewpoint. Of course not the entire scripture is used or the context of the scripture makes no difference, its just the few words that seem like it supports the org. viewpoint.
Several examples of this and im only quoting from what ive been told by witnesses so i dont know exact scriptures, but in the argument about the biblical basis of turning in field service reports they will qoute you a scripture about "good reports" or something by Paul.
We all know the example of door to door service and the scripture the society uses about Jesus instructions to his disciples, which has nothing to do with door to door service.
Another one is the blood issue and God's instructions on spilling blood upon killing animals, where does it state that blood transfusions are banned?
