Of course, non-partisan organizations like Fact Check have disproved most assertions that the President is anti-gun and he has actually been criticized for being too lax on the issue of guns.
Back in my country, my president ... he's trying to pass a gun ban, so he's staging all of these murders, like the 'Fast And Furious' thing down at the border ... Aurora, Colorado, all the people that were killed there ... and now the beautiful people at the Sikh temple. I don't know where I'm gonna live if America keeps going the way it's going because it looks like it's turning into Nazi America.
Moreover, just to clarify; Mustaine is suggesting that President Obama had nearly twenty people killed (12 in Aurora and 6 in Wisconsin)
