Turn about is fair play.
With a little creativity, a pro-gunner could call, say MMM, and ask "advice".
"My son is back from the military, after three tours in Irag,and we have a gun in the house. What should we do?"
Then just feed them along. Ask for statistics. Express "concerns" from an anti-gun parent. Etc. Boy, you ought to get some really juicy replies.
Make the call from VA to a VA number and you may even be able to record the conversation.
Then put the whole thing on YouTube with full disclosure that it wasa sting.
"What you are aboutto hear is how the anti-gunners do not trust..."
