One day after reporter Alison Parker, 24, and her cameraman, Adam Ward, 27, were gunned down on live television in Roanoke, Virginia, Parker's boyfriend said merely remembering their lives is not enough."There needs to be some action that is taken out of an event like this -- out of an event like Sandy Hook, like Charleston, like Aurora, Colorado... where these things just don't occur anymore," Chris Hurst told CNN on Thursday, citing a litany of American gun violence."We need to have a substantive conversation on what is going on in America that is allowing evil to continue to crop up over love? Is it because we are in the media? And the attacker knew this was going to get a lot of play, and here we are again, another mushroom cloud of coverage over gun violence?"On Wednesday, Vester Lee Flanagan II produced a real-time murder show that he choreographed in detail.In a ranting note sent to ABC News before his death, Flanagan blamed his misery on black men and white women and said he was "somewhat racist against whites, blacks and Latinos."
