Bryce Williams, aka Vester Flanagan, the man who shot and killed two journalists live on TV today, once reported on gun control armed with an assault weapon.

The disturbing footage shows Williams holding a submachine gun in one of the several news clips where he's reporting on firearm and race issues.

It's significant ... considering it's believed Williams' motive for gunning down the journalists, who were his former co-workers at Virginia station WDBJ7, is a personal vendetta over racist comments.
