So far, a special thanks to the quality posts by Redneck Riot and BillCA. Thanks also to sikasambared for the insightful opinion and info from Oz.
Now the question posed is, "What happens if Guns are banned?", not, "Do you think Guns will be banned?" Review your post and see which question you answered.
Note: Using nick names and creating short cuts to work around the prohibition on naming candidates and parties here in General Discussion endangers your entire post.
