This was on MSNBC the other day.

Apparently this is racially motivated and all those who carry guns are white racists who are angry about a black man being president.  Strangely they didn't show the man:

I guess showing that this gun was actually carried by a black man would ruin their story of racial motivation.

On the topic of firearms and the media, it's no suprise they're calling this AR15 a "machine gun."

The Media Spin: A black man exercising his Second Amendment rights, carrying a semi-automatic firearm, is portrayed as a white racist right-wing extremist with a machine gun and the intent to do harm to the President.
