Rearing his head from the swirling depths of stupidity, Dave Mustaine, frontman of Megadeth, has claimed that Barack Obama was behind the recent shootings in Colorado and Wisconsin.

TMZ report that he told the crowd at a recent concert in Singapore: "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."

Mustaine also comments, shown in the video below, that: "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."

Mustaine is, of course, no stranger to delivering gleaming insights: he's recently pointed out how "stupid" it is that no-one has, erm, acknowledged Kenya as Obama's birthplace.
