I simply asked a friend of mine to explain to me Deut 20:20-22 and he wrote this:
"Its really quite simple what I think about Deut.18:20-22. I don't. The hebrew scriptures describing aspects of the original Law convenent ended when the new convenent came into place by means of Christ's death."
...im going to be replying to him, anyone have some good comments i can make? or some real hard hitting questions?

I assume you actually meant 18:20-22, the part about false prophets? Cause arguing with a JW about why the OT god instructed Israel to not cut down certain trees seems a bit pointless...
As to questions/comments you can make to him...I am, and have been an atheist for many years...yet I used to be a whole hearted believer, and certain groups of christianity used to annoy me by how they simply dismissed the old testament. I would ask your friend if the OT law was done away with, then what of the ten commandments? What of the blood policy? Why pick and choose, if you're going to accept some of it, why not all of it, and start following the tenet of clean and unclean meats? Or the keeping of the (Saturday) sabbath? This picking and choosing of what parts of the bible to follow was a major contributing factor as to why I became atheist, so many groups out there who were happy to tell me how to live (their version), yet I soon realized, they were dipping from the scriptures where it was convenient for them, and ignoring them where it was not. The JWs are an even worse example of this, they've printed their own version of the bible, complete with new mistranslations and adaptations, made to order.
Sorry to digress a bit...didn't realize after all these years that this issue could get under my skin. Done ranting. Anyway, since the atheist view is highly unlikely to help your friend, here is a link you might like, which you can use to show that the OT law was alive and well in the NT:
