I've seen this article discussed in the past and I just saw this link that was dated for today's news, I guess this is still brewing.
I see that this U.N. Small Arms Treaty is still being talked about. I recently read in the news that Obama said something like, "they were working on some gun control measures under the radar". I wonder if this is what he was referring to? I don't think it would hurt at all for everyone to contact their senators.
