On March 18 - March 28, leaders from across the world will meet to negotiate the first ever treaty that will help prevent keep weapons out of the hands of human rights abusers, such as armed groups and government forces that put children into combat. I hope that you will take the time to send your support of this landmark event. http://www.clickboom.org
This will only mean good. Although it may increase the demand for black market weapons. And therefore the number of them would slowly go down. So, yeah, a good thing like I said.
It could give greater incentive to those who dont care about where their weapons are going (under the table, of course). *Cough* France *Cough*
