Dave, Dave, Dave,  what are you doing?  Why would you stop a metal show to say silly things to a crowd in Singapore about gun violence in America?   About halfway thru the show on August 7th ,  Dave Mustaine went on a somewhat bizarre rant about President Obama and how he 'staged' mass shootings in Aurora Colorado and at the Sikh Temple in Wisconsin. 

As the crowd in Singapore grew quiet Dave said

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!  Back in my country, my president is trying to pass a gun ban, so he's staging all of these murders.

Watch the video to see the whole rant, the Obama blaming comes at approximately 2:38.  Megadeth is currently on the Th1rt3en World Tour.   We can't say that Dave was high on drugs or alcohol, he has been clean for many years and is a born-again Christian.
