It's about a nut job trying to kill a U.S. congresswoman and succeeding in wounding the congresswoman and killing and wounding several others.
And how there is no responsibility due those who said "If we don't win at the ballot box, we'll get them with the bullet box" and “If Ballots Don’t Work, Bullets Will†and "Don't retreat. Instead — reload!" and "If this Congress keeps going the way it is, people are really looking toward those Second Amendment remedies."
