If this were any channel except MSNBC, it would be hard to believe. They show a video clip of a man carrying an assault rifle at an Arizona town hall. The video is edited to not show a full shot of the man. Then, they go on a rant about "racial overtones....white people showing up with guns" and "anger about a black person being president..." The man with the assault rifle was black.
Here is the MSNBC video hiding the race of the gun toter.
Here is a CNN video showing the armed individual is a black man.
